Abstract

China’s construction industry standard “technical code for concrete special-shaped column structure” has been implemented since 2006, and the use of special-shaped walls in the actual construction of buildings is more common. The cross-section wall can effectively reduce the protruding angle of the building, thereby expanding the effective building area of the room, reducing the proportion of the building components themselves, and making the structure layout of the building more beautiful. In order to analyze the dynamic characteristics of eccentrically compressed prestressed concrete beams, the finite element simulation of different reinforcement parameters, longitudinal reinforcement diameter, and reinforcement ratio was constructed. Through comparison, the load flexibility curve change law of concrete stress cloud and reinforcement stress cloud under various working conditions and the influence change law of test mold are studied, and the influence change law of dynamic characteristics under the above four conditions and unidirectional bias pressure is clarified.
基于有限元分析的混凝土材料应力分析
中国建筑行业标准《混凝土异形柱结构技术规范》自2006年开始实施,异形墙在建筑实际施工中的使用较为普遍。横截面墙可以有效地减小建筑的突出角度,从而扩大房间的有效建筑面积,减少建筑构件本身的比例,使建筑的结构布局更加美观。为了分析偏心受压预应力混凝土梁的动力特性,构建了不同配筋参数、纵筋直径和配筋率的有限元模拟。通过对比,研究了各种工况下混凝土应力云和钢筋应力云的荷载柔度曲线变化规律及试验模具的影响变化规律,明确了上述四种工况及单向偏压下的动力特性影响变化规律。
