摘要
本文提出一种新型的钢筋混凝土交叉梁系网架结构。它克服了空腹网架抗剪刚度较差和各杆件中弯矩、剪力分布不均匀的缺点。提出了一种满足工程设计精度要求的近似分析方法,使求解这类高次超静定结构的内力与挠度快速、简捷。并以“空腹型”与“混合型”两类网架结构进行分析对比,从而证明混合型网架结构的优越性。
A new reinforced concrete intersection beam grid structure is proposed, with which the defects of poor shearresistance of open web grid and non-uniform distribution of moments and shears on various members have been overcome.An approximate analysing method which meets the requirment of precision in engineering design and simplifies the solution to internal force and of such highly superstable structure is given.By comparative analysis of 'open web style' and' mixed style', the superiority of the latter is proved.
