【摘要】 柔性边界幕墙索网张拉时,各索间的影响很大,要制定合理的施工保证措施,保证张拉完成后索力满足要求。同时,要采取变形控制措施,保证边界钢结构的变形满足要求。结合实际工程,介绍了柔性边界幕墙索网张拉控制方法,并对仿真计算结果和实测结果进行比较,实测索力和变形与理论计算值相差较小。证明采取的张拉顺序合理,采用伸长值控制张拉,可实现变形和索力双控的目标。更多还原

【Abstract】 The tensile force of curtain-wall cable-net with flexible edge may be affected each other during tension,so reasonable measures are needed to insure the tensile force of cable satisfing correlative demands. At the same time,effective measures are necessary to make the deformation of steel structure be effective. Based on actual project,control tensile force method for the cable-net is discussed.Then,simulated results are compared with monitored ones,and the results show that simulation cable force and deformation approach to monitored ones.It is conclude that the tension sequence is reasonable,the deformation and cable force are ensured by controlling tension value of cable.更多还原
