By using tempered glass as a quake-resistant wall, a loading test was conducted with respect to a tempered glass wall that receives horizontal force and the following findings were obtained: 1. Tempered glass wall that is larger than a size of width 1800 mm x height 1800 mm x thickness 10 mm can support a horizontal load exceeding 100 kN. The maximum horizontal load was 196.7 kN when the thickness of the tempered glass was 12 mm. 2. The load bearing capacity of the tempered glass wall is determined by the buckling of the glass in the case where only the corners are restrained. On the other hand, in the case where all four sides are constrained, the load bearing capacity is determined not by the buckling of the glass but by the rigidity and the strength of the setting blocks that are used on each corner or the locally concentrated stress on the glass. 3. This experiment confirmed that tempered glass has sufficient horizontal load bearing capacity to be used as a quake-resistant wall. It is considered that tempered glass can be practically used as quake-resistant wall by further investigation the construction technique including a sash window frame and setting blocks that are used on the cross section of the tempered glass.
