本文以四層鋼筋混凝土校舍為例，經由歷時皆析及增量震譜分析來比較結構系統在不同窗臺型式、不同柱安排方式、不同翼牆配置型式、以及廊柱有無時之耐震行為。分析比較結果顯示窗臺與柱子隔開、長向柱間距由5m調至3.3m、緊鄰教室隔間牆之柱子強軸轉90°ㄡ及系統有廊柱時，均有助於提高整個校舍結構系統之崩塌地表加速度及能量吸收，並減低地震時之損壞程度。柱子旁增設翼牆時，亦有助於提高系統之崩塌地表加速度，但系統之汰性會受到部份影響。

　　　　　In this paper, the earthquake-resistancy of a four-story RC school building with various construction systems are analyzed compared. The comparison shows that the seperated-breast-wall system, the column spacing adjusted form usual 5m to 3.3m system, the maximum principal axis of the columns adjacent to the classroom partition wall turned 90° system, and the school building with corridor columns can abtain higher system collapse acceleration and absorb more seismic energy. Also, they will reduce the structural damage during earthquake excitation. For the system with column-edge-wall, the collapse acceleration will be improved too, however, the ductility of the system will be affected.
