砖排架是食堂、仓库、健身房、俱乐部、小型厂房等类房屋所常用的一种结构形式。近二十余年来我国发生的多次大地震中,有不少这类房屋遭到不同程度的破坏。其中砖排架柱的震害特征具有明显的规律性:①近山墙的破坏轻,远离山墙的破坏重;②房屋短的,排架柱的破坏程度轻,房屋长的,破坏重。显示出房屋的空间工作特性。《工业与民用建筑抗震设计规范(TJ11—78)》附录1所列的排架地震荷载折减系
Brick fencing is a structural form commonly used in canteens, warehouses, gymnasiums, clubs, and small factories. In the earthquakes that have occurred in China in the past two decades or so, many of these houses have been destroyed to varying degrees. The earthquake damage characteristics of the brick rack columns have obvious regularities: 1 The damage to the gables is light, and the damage from the gables is heavy; 2 The damage to the columns is short, the damage to the columns is light, and the long and heavy houses are destroyed. Shows the spatial working characteristics of the house. Seismic Load Reduction of the Bent Shelf as listed in Appendix 1 of the Code for Seismic Design of Industrial and Civil Buildings (TJ11-78)
