摘要
文中提出一种基于钢索加固剪式结构的三维可展开桥梁;其能快速收缩外,还使用了钢索加固剪式结构,以提高刚度和承载能力。对钢索加固剪式结构与传统剪式结构(无钢索剪式结构)进行静载对比试验,结果表明,钢索剪叉式结构刚度小,结构受力较大,受力不均;采用钢索加强的剪力墙,其剪力墙的刚度有了明显提升,构件截面的应力分布更加均匀;在不影响可展开性的情况下,采用钢索可以提高剪式结构的刚度和承载能力。
In this study,a three-dimensional deployable bridge based on steel cable reinforced shear structure is proposed.In addition to rapid shrinkage,the shear structure is reinforced with steel cables to increase stiffness and load capacity.The static load comparison test between the cable reinforced shear structure and the traditional shear structure(without cable shear structure)is carried out.The results show that the cablefree shear fork structure has low stiffness,large structural force and uneven force.The stiffness of the shear wall strengthened by steel cable is obviously improved.And the stress distribution of the section is more uniform.The practice proves that the rigidity and load-bearing capacity of the shear structure can be improved by using steel cables without affecting the expansibility.
