| 摘 要： | 本文是在文1]基础上的推广与发展。它除有文1]的优点外,其刚度将进一步提高,其内力将更趋均匀,从而达到进一步节约建筑材料和降低工程造价的目的。同时在文2]3]的基础上,提出“预应力混凝土空腹网架结构的近似分析方法”,此法满足结构工程设计要求的计算精度,未知量比空间刚架矩阵位移法大为减少,节约内存、使这种预应力空间刚架结构体系能用低档微机进行计算,以利于这种新型结构的推广。

| Abstract: | This paper is the extension and development of paper1].Except for the advantaeges discussed in paper1],this kind of structure has hi- gher rigidity and its stress tends to be more even.Therefore,the goal of saving building materials and reducing engineering cost can be achi- eved.At the same time,an approximate analytical approach of pre-st- ress concrete open web grid structure is put forward on the basis of pa- per2]and3].This approach will satisfy the requirements of comp- uting precision in engineering desing.Its unknown quantities are much less than those with space frame matrix displacement method.It enables the memory of computer to be saved.Thus this pre-stress space frame- work strtucture system can be handled with low-capacity microcompu ter,and its application can be extended. |
