试验分析还表明，消能支撑框架模型结构的破坏主要集中在底层，即底层是模型结构的薄弱层。
In addition, the analysis indicates the damage of the frame model with energy-dissipation braces concentrates on the ground floor, namely the weak floor.
缺乏必要的技术支撑使得这类结构的风致破坏事故时有发生，所以对开敞式拱形波纹钢屋盖结构的抗风性能进行系统研究己成当务之急。
Because of lacking the necessary technical support, wind-induced damages happen sometimes. So, it is urgent to carry out systematically wind resistant research of such structure.
为研究地下工程格栅支撑这一新型支护结构的力学性能，进行了一系列格栅支撑的小比例结构静力加载试验，分析了格栅支撑的承载力性质和破坏特性。
In order to investigate the mechanical performance of lattice girders, a series of small scale static load tests are carried out and the loading properties and failure behaviour are analysed.
