济南铁路局经十路高层住宅项目结构设计要点分析

Structure Design of High-rise Residence Project of Ji'nan Railway Bureau at Jingshi Road

济南铁路局经十路职工高层住宅项目为现浇钢筋混凝土剪力墙结构,以1号楼为例,从剪力墙布置、剪力墙计算、剪力墙连梁设计等方面论述了剪力墙设计要点。结合设计及规范要求总结了需从规则性判断、整体稳定、刚度比、嵌固端侧向刚度比、周期比、位移比等几个主要方面进行计算结果控制。基础采用桩筏基础。并结合工程实际,采取了平面凹槽处增加连梁及厚板加强,电梯井、楼梯间周边楼板加厚,梁与墙相交处设扶壁柱,主楼与裙房设置沉降后浇带等结构措施加强结构的整体性。

Reinforced concrete shear wall structures are used in the high-rise residential buildings of Ji＇nan Railway Bureau at Jingshi Road. Taking the building No. 1 as an example, the author expounds the key points of shear wall design, from some aspects such as the shear wall distribution, shear wall calculation, tie beam design and so on. Combining with the requirements of the design and the code, and through summarizing, the author points out that, the calculation results should be controlled in view of some factors such as the regularity judgment, global stability, rigidity ratio, lateral rigidity ratio of fixed end, period ratio, displacement ratio etc. In addition, the pile-raft foundation is employed. Furthermore, to enhance the structural integrity, several structural measures are adopted, such as adding tie beams at the groove of the architectural plane, thickening the floor slabs around the elevator shaft and the staircase, installing buttresses at the intersection point between the beam and the wall, and arranging the late-poured band at the junction between the main building and the podiums.
