摘　　要：预应力荷载施加的过程中约束力在柱体内的分布是稳定的;预应力箍筋产生的约束力在柱体纵向沿刚性铰方向进行扩散;在钢筋箍范围之内,宽度较大的垫板约束效果要明显的优于宽度较小的垫板效果。In the pre-stressed load infliction process the binding force The pre-stressed stirrup produces the the rigid articulation direction; In the surpass the width small backing strip binding force longitudinal carries on re-bar hoop scope, the width big effect obviously. in the barrel distribution is stable; the proliferation in the barrel along backing strip restraint effect wants to

关 键 词：约束混凝土 预应力 优化设计
