摘　　要：根据结构特点及现场施工条件,为满足场地受限、脚手架体上部荷载大、工期短、对支撑架承载力及稳定性要求高的混凝土工程施工,可采取插口式与扣件式钢管支架联合搭设的混合支撑架。通过对型钢混凝土组合梁中工字钢焊缝及混合支撑架的现场监测,分析2种架体混合搭设时的受力状况与共同工作情况,并结合混合支撑架的有限元模拟分析组合梁中工字钢对于混凝土浇筑时荷载的传递作用。Based on structure characteristics and on-site situations,in order to satisfy the space restriction,large load on the scaffolding body,the project time is limited,higher bearing capacity and higher stability requirements of the concrete engineering construction,we can use mixed scaffold consist of socket type and fastener-style steel pipe frame formwork-support.Through steel I-beam in the steel reinforced concrete composite beam and mixed scaffold of on-site monitoring,analysis the two kinds of frame body mixed build-up of stress and common working condition,and combining the finite element simulation analysis of the mixed support beams in the range of concrete pouring of load transfer function.
