摘要
对桥式连体结构减震体系地震反应进行了理论推导和数值分析。计算了在El Centro(1940NS)波激励下,连体结构各子结构的地震反应,分析了结构反应与子结构频率比、质量比以及阻尼比的关系,对其影响规律进行了有益探索,并根据底部两结构的振动能量最小的原则,得出了顶部连接部位减震支座优化设计参数变化规律,用以指导减震设计。
Theoretical derivations and numerical analyses on seismic response of bridge-like combined structure system are presented. The seismic response of substructures excited by El Centro （1940NS） wave is calculated. The relationships between the structure response and parameters in substructure such as frequency ratio, mass ratio and damping ratio are analyzed. Some rules of parameters affecting the structural seismic response are analyzed. At last, according to the minimum principle of vibration energy of two components at bottom part, variation rules of optimal design parameters of vibration mitigation bearings of combined structure at top part are presented.
