梁柱节点不同混凝土强度等级的施工处理考虑地震作用组合的框架柱受轴压比控制，为避免柱子断面过大，影响使用功能，常取较高的混凝土强度等级，根据“强柱弱梁”的抗震设防概念，且为不使梁板出现过多的收缩裂缝，梁板的混凝土强度等级往往低于柱的混凝土强度等级，在《... The construction treatment of different concrete strength grades of beam-column joints is considered to be controlled by axial compression ratio of frame columns combined with seismic action. In order to avoid excessive column section and affect the function, a higher concrete strength grade is often used, according to “strong column weak beam”. The concept of seismic fortification, and in order not to cause excessive shrinkage cracks in the beam slab, the concrete slab strength level is often lower than the column’s concrete strength grade, in the "...
