通过２９根有初应力和无初应力构件的试验，了解了初应力对钢管混凝土偏压构件承载力的影响。同时，根据相关方程导得的计算公式，对有无初应力的钢管混凝土偏压构件进行了计算与对比，计算表明这种方法实用可行，所得结果可供设计参改。 Through the tests of 29 elements with initial stress and no initial stress, the influence of initial stress on the bearing capacity of the steel-pipe concrete bias member was understood. At the same time, according to the formula derived by the relevant equations, the calculation and comparison of the prestressed concrete filled steel tube members with or without initial stress are performed. The calculation shows that this method is practical and feasible, and the results obtained can be used for design modification.
