摘要:某办公楼首层和外立面框架柱均为混凝土斜柱,且各层斜柱斜率不一样,称之为连续变向斜柱,斜柱引起楼盖结构产生水平力。对斜柱的竖向抗压刚度和水平抗侧刚度大小进行研究,并推导竖向抗压刚度和水平抗侧刚度的计算公式,结果表明,斜柱竖向抗压刚度远小于普通直柱,水平抗侧刚度大于直柱。对连续变向斜柱斜率不断变化过程中不同层楼盖结构的水平力分布规律进行分析,提出了楼盖水平力较大的结构应对措施。由于连续变向斜柱的存在,不同的施工方案将会造成不同的构件内力分布,通过对施工过程进行模拟分析,选择最合理的施工顺序和拆模周期。

Abstract: The frame columns on the first floor and the fa9 ade of an office building are all concrete inclined columns, and the slopes of the inclined columns on each floor are different, which are called continuously variable-direction inclined columns. The inclined columns cause horizontal forces in the floor structure. The vertical compressive stiffness and horizontal lateral stiffness of the inclined column were studied, and the calculation formulas of the vertical compressive stiffness and horizontal lateral stiffness were deduced. The results show that the vertical compressive stiffness of the inclined column is much smaller than that of the ordinary straight column, the horizontal lateral stiffness is greater than that of the straight column. The horizontal force distribution law of different floors of the floor structure was analyzed in the process of continuously changing the slope of the inclined column, and the structural counter measures for the large horizontal force of the floor were put forward. Due to the existence of continuously changing inclined columns, different construction schemes will cause different internal force distribution of components. By simulating and analyzing the construction process, the most reasonable construction sequence and demolding period were selected.
Keywords: continuously changing inclined column; vertical compressive stiffness; horizontal lateral stiffness; floor horizontal force; internal force distribution; construction process simulation
