摘要
提出一种新型自平衡结构——体内预应力钢屋架。采用等效降温法借助通用软件ANSYS对体内预应力钢屋架进行张拉成型模拟,之后对结构进行静力分析,并与体外预应力钢屋架以及普通钢屋架进行了用钢量比较。通过分析可知,新型体内预应力钢屋架受力性能优越。
A new self-balance structure——internal prestressed steel roof truss was suggested. Using the method of equivalent cooling in the common software ANSYS, the tension forming of internal prestressed steel roof trust was simulated, the static characteristics of the truss were analyzed, and then its dosage of steel was compared with that of external prestressed steel roof truss and normal steel roof truss. The results show that performance of new internal prestressed steel roof truss is excellent.
