[提要]  针对梁板柱混凝土结构施工阶段承担的施工荷载，提出按梁、板两个时变结构，分别计算作用于梁、板以及梁与板上支架的施工荷载，通过支架承担施工荷载的线性叠加计算梁和板共用支架承担施工荷载的简化模型，经实际工程验证，该模型可为施工人员进行模板支撑系统设计与安全检验提供依据。

Through simulating the beam-slab-column structures during construction as two time-dependent structures, namely time-dependent beam and slab structure,loads on the slab, beam and shores are calculated respectively, and the load on the common shore of beam and slab is added linearly. Then a simplified method for beam-slab-column structural construction loads analysis is put forward, and verified with the results of testing in-site, which is the base for the design of construction schedule and checking of temporary structures.
