Foundation Beyeler museum located near Basel, Switzerland is one of the most-visited art museum of the world. Although the entire volume of the museum is not huge, its art collection as well as the well-known museum building designed by Renzo Piano deserve to attract many visitors. The initial design was started in 1991 when the city of Basel decided to fund and support the project. Through a couple of design stages, the museum was finally opened to public in 1997. There have been various research papers dealt with general design issues of Beyeler museum such as composition of exhibition spaces, and natural lighting. However, this paper aims to study the design methods and relationship between art, architecture and nature. Although the museum building is located on the site quietly, there are various specific design solutions to create unique spatial experience of art and nature at each parts. This study focuses on 4 parts of the museum that are located on the main circulation. How art, architecture and nature are integrated together is the main target of the analysis. The analysis is based on visual-perceptual experience and spatial configuration. In chapter 2, general background of the project was studied. In chapter 3, characteristics of the site's natural environment and Piano's design concept's were examined. In chapter 4, each parts were analyzed in detail with diagrams. In chapter 5 & 6, the spatial characteristics were compared together and the fundamental role of the museum architecture was concluded.

This study was conducted under the theory of hermitage ever built from buddhist belief. Directing to hermitages within temples of Korea Jogye Order, we focused on the layout correspondence relationship among them. and 161 hermitages were the first object of the investigation. For the accomplishment of the research purpose, the general epitome and spatial specification through various literature studies, on-the-spot survey and personal communications with a lot of priests were made. As one of the basic surveys, the foundation year were thoroughly investigated, followed by the form of building, main buddha and hermitage name. The results obtained were summarized as follows : Forty five hermitages which are equivalent to twenty eight percent of total hermitages within the parish-level temples of Korea Jogye Order, were built in shilla Dynasty and twenty hermitages that are 12.4 percent of the total were constructed in Koryo Dynasty and thirty seven percent of the total were founded during both of dynasties. This fact makes us to consider that many of hermitages in those days were constructed with the simultaneity of principal temple foundation which means hermitage had responded the spirit of the times. Every hermitage has its main Buddha and this thing happened that each hermitage enshrines its main Buddha according to the thought which was developed with the Buddhism expansion and sutra that is in accordance with their own intention. .Basically a capital temple has differed in its central sanctum in accordance with resourceful sutra, and, at the same time, twenty seven in avatamsk sectenshrine for Sakyamuni as their sanction and eight for the Merciful Goddess and 42.7 percent for Chajang's hermitages. The name of hermitage not only represents its symbol but comprises the characteristic meaning of ascetic practice. 31.7 percent of the hermitages studies was found to have the names of relating to 'ascetic practice' or 'thought' followed by the 'nature' or 'environment' to 21.7 percent.

The effect of soil-structure interaction on a simple single storeyed and two bay space frame resting on a pile group embedded in the cohesive soil (clay) with flexible cap is examined in this paper. For this purpose, a more rational approach is resorted to using the three dimensional finite element analysis with realistic assumptions. The members of the superstructure and substructure are descretized using 20 node isoparametric continuum elements while the interface between the soil and pile is modeled using 16 node isoparametric interface elements. Owing to viability in terms of computational resources and memory requirement, the approach of uncoupled analysis is generally preferred to coupled analysis of the system. However, an interactive analysis of the system is presented in this paper where the building frame and pile foundation are considered as a single compatible unit. This study is focused on the interaction between the pile cap and underlying soil. In the parametric study conducted using the coupled analysis, the effect of pile spacing in a pile group and configuration of the pile group is evaluated on the response of superstructure. The responses of the superstructure considered include the displacement at top of the frame and moments in the superstructure columns. The effect of soil-structure interaction is found to be quite significant for the type of foundation used in the study. The percentage variation in the values of displacement obtained using the coupled and uncoupled analysis is found in the range of 4-17 and that for the moment in the range of 3-10. A reasonable agreement is observed in the results obtained using either approach.

In this seismic analyses of structures, it is well recognized that the effects of soil-structure interaction can not be ignored and seismic responses of a structure taking into account the stiffnesses of a foundation-soil system show the significant difference from those with a rigid base. However, current seismic analyses of apartment building structures were carried out with the rigid base ignoring the characteristics of the foundation and the properties of the underlying soil. In this study, seismic analyses of wall-slob type apartment buildings which have a particular structural type were carried out taking into account the soft soil layer comparing seismic response spectra of a flexible base with those of a rigid base and UBC-97. Low-rise or middle height wall-slab type apartment buildings built on the deep soft soil layer showed a rigid body motion with the reduced seismic responses due to the base isolation effect, indicating that it is considerably safe but uneconomical to utilize the design spectra of UB-97 for the seismic design of wall-slab type apartment buildings due to conservative design.

In this study, a query language was developed to supplement the information retrieval and model regeneration in the case of Industry Foundation Classes (IFC)-based civil infrastructure information models. First, the IFC objects to represent the structural components, entities to manage the related properties, and relationships to connect with the mentioned elements were analyzed in a point of information flow. The results confirmed that the end-users could have problems with access and comprehend the properties and its relationships in the IFC file. Second, the IfcPropertySet-focused query method and applicable stand-alone module were proposed referring to the previous Building Information Model Query Language (BimQL). The availabilities of the proposed method were examined using the rail and sleeper information models through information retrieval and model regeneration. The most important advantage of the proposed approach is the IFC-based information retrievals that can guarantee the interoperability between software packages.

In recent decades, infrastructural development has exploded, particularly in the coastal region of Saudi Arabia. The rising demand of most consumed aggregate in construction can be effectively compensated by the alternative material like scoria which lavishly exists in the western region. Scoria is characterized as lightweight aggregate beneficially used to develop lightweight concrete (LWC) - a potential alternative of normal weight concrete (NWC) ensuring reduction in the structural element's size, increase in building height, comparatively lighter foundation, etc. Hence, the goal of this study is to incorporate scoria-based structural lightweight concrete and evaluate its impact on superstructure and foundation design beside contributing to the economy of construction. Fresh, mechanical, and rheological properties of the novel LWC have been investigated. The structural analyses employ the NWC as well as LWC based structures under seismic and wind loadings. The commercial finite element package - ETABS was employed to find out the change in structural responses and foundations. The cost estimation and SWOT analysis for superstructure and foundation have also been carried out. It was revealed that the developed LWC enabled a more flexible structural design. Notable reduction in the steel and concrete prices of LWC might be possible in the low-rise building. It is postulated that the cost-effective and eco-friendly LWC will promote the usage of scoria as an effective alternative in Saudi Arabia and GCC countries for structurally viable LWC construction.

Recently, the number of high-rise buildings being built in Korea by major construction companies for residential and commercial use has been increasing. When constructing a high-rise building, it is necessary to apply massive amounts of concrete to form a mat foundation that can withstand the huge load of the upper structure. However, it is of increasing concern that due to limitations in terms of the amount of placing equipment, available job-sites and systems for mass concrete placement in the construction field, it is not always possible to place a great quantity of concrete simultaneously in a large-scale mat foundation, and for this reason consistency between placement lift cannot be secured. In addition, a mat foundation Is likely to crack due to the stress caused by differences inhydration heat generation time. To derive a solution for these problems, this study provides test results of a hydration heat crack reduction method by applying placement lift change and setting time control with a super retarding agent for mass concrete in a large-scale mat foundation. Mock-up specimens with different mixtures and placement liftswere prepared at the job-site of a newly-constructed high-rise building. The test results show that slump flow of concrete before and after adding the super retarding agent somewhat Increases as the target retarding time gets longer, while the air content shows no great difference. The setting time was observed to be retarded as the target retarding time gets longer. As the target retarding time gets longer, compressive strength appears to be decreased at an early stage, but as time goes by, compressive strength gets higher, and the compressive strength at 28 days becomes equal or higher to that of plain concrete without a super retarding agent. For the effect of placement lift change and super retarding agent on the reduction of hydration heat, the application of 2 and 4 placement lifts and a super retarding agent makes it possible to secure consistency and reduce temperature difference between placement lifts, while also extending the time to reach peak temperature. This implies that the possibility of thermal crack induced by hydration heat is reduced. The best results are shown in the case of applying 4 placement lifts.

This paper discusses the design parameters that are required for the design of high-rise building foundations, and suggests that the method of assessment for these parameters should be consistent with the level of complexity involved for various stages in the design process. Requirements for effective ground investigation are discussed, together with relevant in-situ and laboratory test techniques for deriving the necessary strength and stiffness parameters. Some empirical correlations are also presented to assist in the early stages of design, and to act as a check for parameters that are deduced from more detailed testing. Pile load testing is then discussed and a method of interpreting bi-directional tests to obtain pile design parameters is outlined. Examples of the application of the assessment process are described, including high-rise projects in Dubai and Saudi Arabia.
