摘要
从框架柱弯矩调整系数、抗震构造措施等方面对我国新旧建筑抗震设计规范(GB 50011-2010和GB 50011-2001)关于"强柱弱梁"上规定的差异进行了比较分析,详细地分析了影响"强柱弱梁"实现的主要因素。采用新旧两个抗震设计规范分别对抗震等级为一、二、三级的3个钢筋混凝土现浇楼板框架结构进行了计算分析,分别计算新旧两个规范下,考虑现浇楼板及其钢筋对框架梁抗弯承载力的贡献时节点处柱梁端实际抗弯承载力比,并对其进行了比较分析。
The differences of strong-column weak-beam between the new and old code for seismic design of buildings （GB 50011-2010 and GB 50011-2001 ） are analyzed comparatively from moment magnifying coefficients at column ends of frames and details of seismic design,and the main factors of ensuring strong-column weak-beam are analyzed in detail. Three RC frame structures with casting slab of seismic grades in the first, second and third grade are calculated respectively and designed by the new and old codes for seismic design of buildings, and considering the contribution of the slab and its reinforcements the ratio of actual column-to-beam flexural strength at joint are calculated and analyzed comparatively under the new and old codes for seismic design of buildings.
