摘要
本工程为超长结构,水平向最大长度达226 m,未设缝,补充了温度应力计算,并采取其它构造措施控制楼板裂缝。平面存在凹凸不规则和楼板局部不连续,补充中震弹性计算,并根据计算结果,对楼板连接薄弱处予以加强。对于扭转不规则,则利用楼梯间设置型钢混凝土斜撑控制建筑物的扭转。对于下沉广场处一层楼板大开洞,采用嵌固在地下室顶板和嵌固在地下一层楼板模型包络设计配筋。
The project is an overlength structure.The maximun length in horizontal direction is up to 226m.There is no structural joint.Temperature stress analysis and the other structural measures was supplemented to contral the floor cracking.There is Concave Convex Irregularity and Floor Locally Discontinuous in the plan.The caculate of the elastic of moderate erthquake was supplemented,and the weak connection of the floor slab was reinforced based on the result of the caculate.To the torsional resistance,the steel reinforced concrete oblique supports was supplemented to contral the torsion of the building.To the big open hole by the sunken plaza on the first floor,the enveloping method of first floor and the ground floor partial fixing of the building was supplemented to design the structural element.
