体内预应力钢屋架结构稳定性的参数研究

Parameter Study on Stability of Internal-prestressed Steel Roof Truss

体内预应力钢屋架是一种新的预应力钢结构形式。作者研究了该结构在张拉成型过程中的内力分布以及参数影响因素,讨论了该结构成型后的稳定性问题,确定影响成型后结构稳定性的关键参数,为该类结构的设计和加工提供依据。

The internal-prestressed steel roof truss is a novel prestressed steel structure. The internal force and parameter study in its erection process have been studied by the authors. In this paper, the stability of the erected structure is discussed. The key parameters affecting the stability are determined. This will provide a reference for the design of such structures.
