Firstly,authors studied the reasons that results in the secondary internal force were caused by prestressing force in PC continuous beam.
首先分析了预应力混凝土连续梁中预应力引起的次内力产生的原因,然后把连续梁等效成边跨和中跨2种基本结构形式,将常见预应力束布设形式引起的固端约束次力矩和弯矩用参数表示,包括直线束、局部束、折线形预应力束以及抛物线形预应力束;同时,分析了折线束和抛物线束的梁端压力线与梁重心线的偏离距率及钢束几何形状的对应关系,总结了这2种布束形式对结构内力影响的特征;最后以一个三跨等截面连续梁为实例,对比折线束与抛物线束产生的次内力效应。
