A pilot study has been conducted to guide the development of a finite element modeling formulation for the analysis of architectural glass curtain walls under in-plane lateral load simulating earthquake effects. This pilot study is one aspect of ongoing efforts to develop a general prediction model for glass cracking and glass fallout for architectural glass storefront and curtain wall systems during seismic loading. For this study, the ANSYS finite element analysis program was used to develop a model and obtain the stress distribution within an architectural glass panel after presumed seismic movements cause glass-to-frame contact. The analysis was limited to static loading of a dry-glazed glass curtain wall panel. A mock-up of the glass curtain wall considered in the analysis with strain gages mounted at select locations on the glass and the aluminum framing was subjected to static loading. A comparison is made between the finite element analysis predicted strain and the experimentally measured strain at each strain gage location.

This Study is concerned with the present condition and prospect of architectural stained glass in Korea. Stained glass had been architectural art from the origin. But it had declined since the Renaissance era, and began to revive in the early 20th century. The stained glass inflowed with church architecture occasionally by the western missionaries. And it has been developed actively since 1980' with the boom in church building. There are about 30 studios which are making stained glass in Korea, but very few studio work true architectural stained glass. Stained glass is still treated as simple decoration or 2-dimensional mosaic. Architect and interior designer even have little understanding of architectural character of stained glass.I have considered the problems and prospected architectural stained glass which inspire modern architecture with human sensitivity in Korea.

This study is concerned with the process of development and architectural characteristics of secular stained glass in the 20th century. Stained glass had been architectural art from the origin. But it had declined since the Renaissance era, and began to revive in the early 20th century. Stained glass work is very flourish in Korea today, but it is still treated as simple decoration or 2-dimensional mosaic. Architect and interior designer even have little understanding of architectural character of stained glass. In order to recover the architectural nature of stained glass, I have considered the process of development of secular stained glass in the 20th century, and analysed the works of Frank Lloyd Wright, the postwar German artists, Georg Meistermann, Ludwig Schaffrath, Johannes Schreiter, and English artist, Brian Clarke. Major findings of the study are as followings : First, stained glass has come to life again from the secular glass painting decoration in the end of the 19th century, through Art-Nouveau, De Stil, Bauhaus in the beginning of the 20th century, and L'Art $Sacr\acute{e}$. Second, Frank Lloyd Wright, the postwar German artists and Brian Clarke have established the architectural concept and potentiality of the modem stained glass in the secular field. Third, They have done by coming back to the basic creative method by traditional lead-came technique in spite of the development of various materials and techniques. Forth, stained glass fundamentally has architectural characteristics as the characters of Space, Time, Place, Context, and they have showed the new possibility of stained glass by recovery of these characters.

The main goal of this study is to examine the current status of architectural glass in terms of its risk for inflicting injury in elementary schools, middle schools, and high schools. Through objective analysis of data contributed by the investigation of the cause, degree of seriousness, and bodily location of injury, the hazardousness of architectural glass in educational facilities will be evaluated. Most importantly, this study is an attempt to increase awareness of the need for establishing a safety standard in the installation of safety glass in order to prevent injuries inflicted by architectural glass in educational facilities.

This study investigated the possibility of strength development by incorporating the slighly coarser soda-lime glass powder (GP) with 0-100 wt.% of Ground Granulated Blast Furnace Slag (GGBS) to synthesis GGBS based geopolymer. Compressive strength, water absorption & apparent porosity, were experimentally determined. To determine the homogeneity of mix, the microstructure & elemental composition of samples were studied using SEM-EDS. Study reveals the improvement in strength and reduction in porosity for the samples containing up to 30% GP. Furthermore, the microstructure analyses confirmed the development of denser and compact structure with the incorporation of glass powder up to 30%.

In contemporary architecture, glass is being used less as a single piece for the exterior envelope, due to a variety of influences such as increased performance regulations, the market environment and technical developments. An architectural exterior wall today is usually installed as a 'ystem' wall, not as a single plane glass wall. That brings up the necessity to question the appropriateness of the materiality of an individual piece of glass for the exterior envelope in urban settings. Therefore, in many cases it is appropriate to examine materiality of glass as a system. A new examination of materiality can be carried out by analyzing the interactions between layers that constitute a system. This paper examines the experimental use of glass systems in contemporary architecture, and analyzes them to interpret the relationship between the layers of each system in order to establish the diversified materiality of glass in contemporary architecture.

The study of the expression of architectural glass has recently expanded due to various factors such as the development of architectural technology, the reinforcement of environmental standards, an increased interest in energy saving, and the commercialism of the exterior of buildings. The background for restoring the tactile capability of the sense of sight has been prepared by agitating oculocentricism pertaining to the Renaissance era. The restoration of tactility can be considered in two ways. One is the tactility 'perceived' through complex experiences and the other is the tactility 'sensed' from the challenges on the materiality of the glass itself. Perceptual tactility is achieved from compound visual experiences and connecting these complex experiences in the brain. Sensible tactility, in contrast to perceptual tactility, is a more direct tactility which works within the nervous system, bypassing the brain. This is attained by reversion of the materiality, tectonics and connection method of the glass. Among rare examples, Laminata House built in Leerdam, Netherlands is a fine example of direct and sensible tactility. In this paper, the process of restoring tactility in architecture is studied at each stage based on the restoration of tactility in painterly aesthetics.

The use of carbon fibers (CF) and glass fibers (GF) were combined to strengthen concrete flexural members. In this study, data of tensile tests of 94 hybrid carbon-glass FRP sheets and 47 carbon and GF rovings or sheets were thoroughly investigated in terms of tensile behavior. Based on comparisons between the rule of mixtures and test data, positive hybrid effects were identified for various (GF/CF) ratios. Unlike the rule of mixtures, the hybrid sheets with relatively low (GF/CF) ratios also produced pseudo-ductility. From the calibrated results obtained from experiments, a new analytical model for the stress-strain relationship of hybrid FRP sheets was proposed. Finally, the hybrid effects were verified by structural tests of concrete members strengthened with hybrid FRP sheets and either carbon or glass FRP sheets.

This study incorporates fine waste glass (GS) as a replacement for natural sand (NS) in fly ash (FA) based alkali activated mortar (AAm). AAms were heated at elevated temperature of 200℃, 400℃, 600℃, and 800℃ to explore the residual mass, compressive strength, thermal expansion and change in microstructure of matrix. Results showed greater resistance of AAms with increasing GS content to 50% at each temperature. Owing to the melting of GS at 800℃, the greater matrix bond was observed for AAm incorporating 75% and 100% GS as a result, the residual compressive strength was increased.

Standard finite element wave propagation codes are useful for determining stresses caused by the impact of one body with another; however, their applicability to a laminated system such as architectural laminated glass is limited because the important interlayer delamination process caused by impact loading is difficult to model. This paper presents a method that allows traditional wave propagation codes to model the interlayer debonding of laminated architectural glass subject to low velocity, small missile impact such as that which occurs in severe windstorms. The method can be extended to any multilayered medium with adhesive bonding between the layers. Computational results of concern to architectural glazing designers are presented.
