【摘要】 采用增量动力分析(Incremental Dynamic Analysis,IDA)方法,得到了对称和不对称连体结构在地震作用下消能连廊破坏的临界地震峰值加速度,并对在该峰值加速度下消能连廊的破坏进行了模拟。IDA分析结果表明,不对称结构消能连廊较对称结构更易发生破坏,近断层地震作用下消能连廊破坏的危险性较远场地震下的要大。同时,破坏模拟表明,消能连廊的破坏一般是由于连廊支座位移超限引起的。更多还原

【Abstract】 Using the method of incremental dynamic analysis(IDA),the energy dissipation corridor critical damage PGA of the earthquake under the symmetry and un-symmetry connected structure is determined,then the damage simulation of the energy dissipation corridor under the PGA is carried.Incremental dynamic analysis result shows that the energy dissipation corridor of the un-symmetry connected structure is easier to damage relative to the symmetry structure.Compared with the far field seismic motion,the damage probability of the energy dissipation corridor is large than the near-fault seismic motion.Meanwhile,the damage simulation shows that the damage of the corridor is generally caused by the over limits displacement of the corridor bearings.更多还原
