摘要:
综合考虑网壳结构杆件的失稳与失效,利用ANSYS/LS-DYNA 软件建立网壳结构的数值模型,分析判别了网壳结构
在强震作用下的倒塌破坏模式,包括动力强度破坏、动力失稳破坏和综合破坏三个类型.接着将铅阻尼器以能量等效的原则
加入到网壳结构中,在三条不同地震波激励的情况下,分析了铅阻尼器减振系统对网壳结构倒塌模式的影响.结果证实:加
入铅阻尼器减振系统之后,网壳结构的倒塌临界荷载被提高了1.11 倍,同时网壳结构中的屈服杆件比例提高了3.29 倍,与
未加铅阻尼器减振系统的情况相比,网壳结构更倾向于发生动力强度破坏.
Abstract:
Abstract: The numerical model of reticulated shell is constructed by ANSYS/LS-DYNA software, in which both the failure and
instability of the member of the structure are considered. The collapse mode of reticulated shellunder strong earthquakesis obtained
from analysis, includingdynamic strength failure and dynamic instability failure and complex failure due to the above two
factors.Subsequently, the seismic responses of reticulated shell with lead damper systemunder three different earthquakes are
analyzed,in whichthe lead dampersare embedded into the structure based on energy equivalence principle. It can be concluded that
the critical load of collapsedof the structure under strong earthquakesis increased by 1.11 times, and the ratio of yield
memberisincreased by 3.29 times.The structure with lead damper systemtends to be damaged in the form of dynamic strength failure
compared with the structure without lead damper system.
