体内预应力钢屋架结构的设计思路

Design of Internal-prestressed Steel Ro of Truss

体内预应力钢屋架是一种新的预应力钢结构形式,其设计方法有待完善。作者在该类结构成型过程内力分布和成型后承载力的参数研究工作基础上,提出了体内预应力钢屋架结构的总体设计思路,建立了关键结构参数的经验公式。

The internal-prestressed steel roof truss is a novel prestressed steel structure.Its design method requires improving.In this paper,based on the parameter study on the internal force in its erection process and on the bearing capacity after erection,the design method for such structure is proposed,and the empirical formulas of key parameters are established.
