摘要
本文从理论上和实验上研究了配筋水泥刨花板受弯构件(主要是折板)在荷载作用下的基本性能,提出了两种不同的破坏模式并进行了验证与分析.将结构分析的有限条法用于分析受弯构件,并用Pascal语言编制了可以模拟实验过程,用以计算承载力、挠度、含钢率以及进行截面设计的适用性较强的源程序.通过电算,进行了受弯构件的参数分析,并给出了最大、最小含钢率的算式.
The theoretical and experimental research on the reinforced wood—fiber concrete(RWC)bending members (mainly folded-plates)is carried out in this paper. Two different forms of fracture are introduced and verified by experiments on slabs. The finite strip method is used to analyse beams and folded-plates, especially those made of wood-fiber concrete and reinforced by steel belt. A program in pascal language is designed. It can simulate loading experiment to calculate the loading capadty, deflection and steel ratio of a bending member, it can also design the size of a cross—section, so it can be widely used in structure analysis. By computering, the efects of various factors on working behavior of a bending member are analysed, and formulars are initially deduced to calculate the maximum and minimum of steel ratios in bending members.
