摘要
基于目前超高层建筑每层施工的时间越来越短的情况,缩短施工周期有利于加快工程进度,以及施工材料的周转,提高施工企业效益,然而施工周期缩短将导致混凝土强度还没达到100%就要将模板拆除,将加大楼层承担的最大施工荷载,对结构安全带来不利影响,通过理论计算分析以及工程实例对大跨梁的受力情况进行论证。
Based on the fact that the construction time of each floor of ultra-high-rise buildings is getting shorter and shorter,shortening the construction cycle is conducive to accelerating the progress of the project,as well as the turnover of construction materials,and improving the efficiency of the construction enterprise.However,shortening the construction cycle will cause the strength of the concrete to reach 100%the formwork will be dismantled,which will increase the maximum construction load on the floor,which will adversely affect the structural safety.The theoretical analysis of the calculation and the engineering examples will be used to demonstrate the behavior of the long-span beam.
