Building frame supporting structure
The invention provides a building frame supporting structure. The building frame supporting structure comprises a plurality of layers of supporting units arranged in an up-down stacked mode, wherein each supporting unit comprises a left frame column, a right frame column, a first frame beam, a second frame beam, a first support, a second support, a third support and a fourth support, the resistance design values of the left frame columns and the right frame columns meet the conditions that R/gamma is greater than or equal to eta * S; R/gamma is greater than or equal to eta * S; R/gamma is greater than or equal to eta * S; and R/gamma is greater than or equal to eta * S. According to the building frame supporting structure, by limiting the resistance design values of the left frame columns and the right frame columns, when a rare earthquake exceeding the seismic fortification intensity occurs, plastic deformation energy consumption of the structural support can be performed firstly, plastic deformation energy consumption of the frame beams can be performed later, and the frame columns cannot be damaged, so that local collapse or overall collapse of the building structure is avoided, and building structure safety and life and property safety are ensured.
本发明提供一种建筑框架支撑结构，包括多层上下层叠布置的支撑单元，所述支撑单元包括：左框架柱、右框架柱、第一框架梁、第二框架梁、第一支撑、第二支撑、第三支撑以及第四支撑；所述左框架柱和所述右框架柱的抗力设计值满足：RCLTi/γRE≥η·SCLTi；RCLBi/γRE≥η·SCLBi；RCRTi/γRE≥η·SCRTi；RCRBi/γRE≥η·SCRBi。本发明通过对左框架柱和右框架柱的抗力设计值的限定，当发生超出抗震设防烈度的罕遇地震时，能够使结构支撑先发生塑性变形耗能，框架梁后发生塑性变形耗能，框架柱不会发生破坏，从而使建筑结构避免局部坍塌或整体倒塌，保证建筑结构安全和生命财产安全。
