    This paper presents the flexural capacities of biaxial hollow slabs with donut type hollow shapes. Recently, various types of slab systems which can reduce self-weight of slabs have been studied as the height and width of building structures increase. A biaxial hollow slab system is widely known as one of the effective system which can reduce self-weight of slab. A biaxial hollow slab has hollow spheres within slabs in order to reduce self-weight of slabs. The capacities of biaxial hollow slab are influenced by the shapes, volume of hollow spheres. According to analytical studies, the hollow slab with donut type hollow sphere had good flexural capacities such as strength, stiffness and deflection. To verify the flexural capacities of this hollow slab such as strength and stiffness, flexural tests were performed. Three test specimens were planned to verify the effect of test parameters. One was conventional RC slab and others were donut type hollow slabs. The donut type hollow slabs have two different fixing methods of plastic balls. The one is used diagonal steel cage and the other is fixed with only its geometrical shapes without additional steel cage.

    This paper aimed at modeling a triangular mesh for network dome by using differential evolution algorithm. For this purpose, an optimization process to find a regular triangular mesh on the curved surface was proposed and a program for this was developed. The objective function consisted of the standard deviations of the area and the boundary length of each triangle, and the design variables were regulated by the upper and lower boundary conditions which were calculated depending on the nodal connectivity. Plate model and triangular network dome model, which initially had consisted of irregular triangular meshes, were selected as target examples. In the case of the plate model its final mesh corresponded with the regular triangular mesh exactly. In network dome model, its result was very approached to the minimum standard deviation of the area and theboundary length of each triangle, too. Additionally, the more rise-span ratio of the dome decreased, the more the standard deviation of the mesh modeling decreased.

    In this study, a double beam system was proposed to reduce the deflection of reinforced concrete beams. The system consists of two small size beams and a drop panel. The proposed method took into account the effect of a drop panel placed at the center of the continuous beam. Because the drop panel increases the negative moment of the beam, but decreases the positive moment of the beam, it is expected that the drop panel might reduce the deflection of continuous beams. Five reinforced concrete continuous beams were tested. The main parameters of specimens were the length and width of drop panel. Test results indicated that the drop panel reduced the deflection of continuous beams. The deflection of the continuous beams with a drop panel was 24. 5 percent less than that of the beams without a drop panel. The deflection of continuous beams was decreased with the increase of the length of drop panel.

    Concrete filled steel tube column is one of the best methods to increase the structural efficiency using its constitutive material's complementary properties. But, the limitation of material strength in present design code is a big obstacle to enhance the high strength materials. The purpose of this study is to evaluate the axial load capacity in present design code in high strength materials by analyzing previous research results. The materials using this study are test results by several researchers from 2002 to 2012. Test results of total 88 specimens are analyzed with the AISC 360-10 code and B.Uy's proposed formula. Analytical results indicated that present design code approximately well estimate the axial load capacity below 600MPa of the steel yield strength regardless of the class of section type. But, it is necessary to revise the load capacity in high strength steel especially in non-compact element because it underestimate their design strength compared with test results.

    Since 1970s, the rapid urbanization process by industrial and economic development in Korea causes to a severe change of surface roughness and recent abnormal weather by global warming causes to increasing the intensity of strong wind and Typhoon. It is necessary to revise basic wind speed map of Korean Building Code 2009(KBC-2009) drowned by past meteorological data from 1951 to 1995. This paper proposes new basic wind speed map corresponding to a return period of 100 years in Korea. The values are established from data of annual-maximum 10-minute mean wind speeds collected at 68 meteorological offices recent past 40 years from 1973 to 2012. They were standardized homogeneously to an altitude 10m above the surface roughness category C. Surface roughness category was determined by surrounding surface conditions of meteorological station in 1999 and 2012. The data were statistically reduced using extreme value analysis procedures based on Gumbel's distribution, and the expected wind speeds corresponding to a return period of 100 years (it is called as basic wind speeds) were calculated for each region. The equivalent wind speed contour line to a return period of 100 years were drown up interval of 2m/s to the map of Korea. The basic wind speeds of this study were compared with those of KBC-2009, and the causes of wind speed up or down were described. The basic wind speed map of this study shall be used to revise that of KBC-2009.

    Sprayable fiber reinforced strain-hardening cement composites(SHCCs) were developed for seismic retrofitting of existing infrastructures, especially, for packing the joint between existing R/C building and seismic retrofit elements. In this paper, influence of mixture proportions on the mechanical properties, such as compressive, flexural and direct tensile performances, of sprayable SHCCs is investigated. Sprayable SHCCs developed in this study were reinforced with synthetic PVA fibers at the volume fraction of 2.2%. Mechanical properties of SHCCs were evaluated on the specimens manufactured after mixing, pumping, and shotcreting. The test results indicate that the compressive strength and elastic modulus of three SHCC mixtures increased almost linearly according to shotcreting procedure from mixer to nozzle. And the direct tensile and flexural behavior of SHCC mixture(SHCC-C) with AE agent was superior to the those of the other SHCC mixtures(SHCC-A and-B). It also has very high pumpability and sprayability characteristics.

    Recently, it is certain that the increase of heating and cooling energy consumption by radical change in climate condition has caused serious problems related to environmental and energy concerns associated with increase of fossil fuel usage and carbon dioxide production as well as global warming. Therefore, various actions to reduce greenhouse gas and energy consumption have been prepared by world developed countries. Our government has also been trying to seek energy control methods for houses and buildings by proclaiming political polices on low-carbon green growth and construction and performance standards for environment-friendly housing. The energy consumption by buildings approximately reaches 25% of total energy consumption in korea, and the increasing rate of energy consumption by buildings is stiffer than that of the other industries. The biggest consuming building element is building facade. While lots of research projects for reducing energy consumption of the facade have been conducted, few research projects on concrete covering more than 70% of outsider of buildings has been tried. This research presents here a study to improve the insulation property of structural concrete by calcined diatomite powder and lightweight aggregate with experimentally reviewing the physical, mechanical and thermal conduction characteristics of the concrete. The result of experiment showed calcined diatomite powder 10% series mixtures resulted in positive workability, compressive strength and resulted of thermal conductivity, which was the improvement of 43% compared to plain. In the future, various studies must be progress that review of various insulation performance improvement materials, review of performance and durability of the structure in order to field application and improve insulation performance of concrete.

    As global warming is higher by $CO_2$, most of countries have an effort to develop $CO_2$ reducing technology like a $CO_2$ sequestration and a $CO_2$ curing method using cement based materials. In this study, $CO_2$ uptake rate, compressive strength and length were investigated when $CO_2$ curing method was applied in cement mortar. The $CO_2$ uptake rates were ranged from 10.1 % to 11.6 %, average 10.5 % by mass measurement method. On the early compressive strength, 1 hour $CO_2$ curing specimens were higher than 1 hour atmospheric curing specimens but lower than 5 hours steam curing specimens. As time was elapsed until 28 days, the compressive strengths of specimens by atmospheric curing and steam curing were similarly increased both. But the compressive strengths of 1 hour $CO_2$ curing specimens were lower than other two curing methods. The dry shrinkage rates of 1 hour $CO_2$ curing specimens were lower than those of other two curing methods by pore-filling effect of carbonation.

    Cement is an important construction materials in the world. However, cement industry the emit carbon dioxide($CO_2$) which is a byproduct of a chemical conversion process used in the production of clinker into the atmosphere. Also, carbon dioxide is also emitted during cement production by fossil fuel combustion. There has been a lot of research in order to protect the global environment and to reduce the consumption of cement. This experimental study is purposed to analyze the effect of alkali activator on strength development in order to develop non portland cement concrete using waste resources(paper sludge ash, blast furnace slag and red mud). Various specimens were prepared with water binder ratios and replacement of red mud of alkali activator. The physical properties of these specimens were then investigated by compressive strength and flexural test, energy dispersive spectroscopy(EDS) and observation of micro-structures using scanning electron microscope(SEM). As a results, we find that compressive flexural strength increased with the addition ratios of red mud, but those strengths decreased reversely when addition ratio of some alkali activator were higher. In the EDS of matrix, the calcium hydroxide was possible to quantitative analysis in accordance with water binder ratios and replacement of red mud of alkali activator respectively. The observation result of SEM image, it was shown calcium hydroxide, C-S-H gel etc.. It was judged that results of hydrate analysis of non potland cement matrix binder with kind of water binder ratios and replacement of red mud of alkali activator were useful to basic data for mixtures design and evaluation properties of non portland cement matrix concrete.

    The selection of appropriate materials plays a very important role in satisfying the customer in terms of construction project quality, cost and process. Therefore, accurate construction material information analysis is necessary. Designers with little experience in construction material selection, however, make choices without understanding the characteristics of different construction materials, which lowers the quality of the construction. Material information documents are distributed in personal computer without document management system. This paper suggests document management module that composed tag-manager, server and search interface for systematic using of material information documents. Construction material information document prototype system is developed to support member of material company. The effectiveness and efficiency of the developed prototype system was confirmed through interviews with construction material company staffs. There is a need for further studies, though, that will expand the users of the developed prototype system and that will improve the tag information and the system.
