This paper deals with the experimental study of the eartuquake resisting wall using toughened glass. Load bearing tests were conducted to determine the ultimate horizontal strength and deformation capacity. The result shows the wall using toughened glass has enough strength as the earthquake resisting wall for wooden house.

Glass panes used for fire protection windows has not only flame barrier performance but also parts requiring scattering prevention performance, crime prevention performance and impact resistance in the event of breakage of the glass in some cases, laminated glass is often used . In general, Poly Vinyl Butyral is used as the interlayer. Furthermore, in combination with Low-E glass which has become very popular in recent years, combined double glazing glass which has a radiant heat reduction effect is also used. Fire protection window with tempered fire resistance glass has passed the certification test based on know-how of each manufacturing company so far and has been adopted after various fire certification, but there are not standards for ensuring clear fire prevent performance. Regarding heated glass on fire, the test data was accumulated on the single glass, the insulated glass unit (IGU) and the Low-E IGU based on the fire test, and the thermal stress generated in the glass can be explained by grasping the temperature difference were revealed. However, the temperature properties of the laminated glass composed of the tempered fire resistance glass to be heated are not systematically clarified, and it is necessary to obtain basic knowledge. Therefore, in this study, considering the behavior of laminated glass and laminated IGU made of tempered fire resistance glass which is heated based on the knowledge obtained in the previous report. The fire test condition is shown below. ·These fire tests were performed for Laminated glass and Laminated IGU. ·Tempered fire resistance glass was mainly located on fire side. ·Fire tests were performed along the ISO834 Heat Curve for each specimen. ·The temperature of the glass was measured by thermo couples with a data logger. ·Surface Compression, Edge Cover of Glass, and Emissivity of Low-E glass were treated as parameters for heat stress of glass, ΔT and breakage factor of the glass were checked by fire tests. ·Laminated glass by heating is affected by the interlayer, its behavior is confirmed. Findings are as follows. (1) As the temperature difference between the glass surface and the edge increases, high surface compression stress is required. (2) The temperature difference between the glass surface and the edge increases as edge cover becomes deep, and the glass tends to break more easily. (3) The interlayer of the laminated glass foams and a layer of air is formed, and the temperature of the surface of the unheated side glass tends to be low. When the interlayer foams by heating, a foamed part and an unfoamed part are generated. (4) If Low-E glass is used in laminated IGU, the emissivity of Low-E glass influences the foaming time of the interlayer and the failure behavior of the unheated side glass. (5) Transmission of radiant heat flux of laminated glass and laminated IGU on fire was estimated.
