[提要]  針對(duì)梁板柱混凝土結(jié)構(gòu)施工階段承擔(dān)的施工荷載，提出按梁、板兩個(gè)時(shí)變結(jié)構(gòu)，分別計(jì)算作用于梁、板以及梁與板上支架的施工荷載，通過(guò)支架承擔(dān)施工荷載的線(xiàn)性疊加計(jì)算梁和板共用支架承擔(dān)施工荷載的簡(jiǎn)化模型，經(jīng)實(shí)際工程驗(yàn)證，該模型可為施工人員進(jìn)行模板支撐系統(tǒng)設(shè)計(jì)與安全檢驗(yàn)提供依據(jù)。
[關(guān)鍵詞]  混凝土結(jié)構(gòu)  施工階段  時(shí)變結(jié)構(gòu)體系  施工荷載  安全檢驗(yàn)

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.
Keywords:  beam-slab-column concrete structure; construction process; time-dependent system; loads; safety
