依景花园A1栋 高层住宅楼结构设计
摘 要
本工程为依景花园A1栋，拟建高层住宅楼。根据现场的土地使用面积将该楼设计成一对称布置的住宅楼，设置一部电梯，一层设置四户。首层的标高为3.9米，其余11层的层高均为2.9m。楼层总高度为35.8m。总建筑面积4319.28m2。基本风压值0.65kN/m2，抗震设防烈度7度，设计基本地震加速度值为0.10g，Ⅱ类场地，设计地震分组为第一组。
本工程结构设计采用框架-剪力墙结构，结构计算按纵向框架承重分析。具体内容包括：结构方案和初选截面尺寸；楼板结构设计；结构计算简图及刚度参数计算；荷载计算及结构位移验算；水平荷载作用下的结构内力分析；竖向荷载作用下的结构内力分析；荷载效应及内力组合；截面设计和构造要求；基础设计；结构施工图的绘制；计算机辅助设计。在进行截面抗震设计时，柱按偏压构件计算，保证延性框架要“强剪弱弯，强柱弱梁，强节点弱构件强锚固”的设计原则，且满足构造要求。

A1 Block Of King Garden In High-rise Residential Buildings,
Structural Design
Abstract
King Garden in the works for A1 block, the proposed high-rise residential buildings. According to the land use area will be carried into a symmetrical layout design of residential buildings, the installation of a lift, one of four households. The level of the first floor is 3.9m and the remaining eleven floors are 2.9m high-level layers. The total height of the building is 35.8m. A total construction area is 4319.28m2. Basic wind pressure value is 0.65kN/m2, earthquake intensity of 7 degrees security, the basic design for seismic acceleration values 0.10g, category II sites, design for the earthquake-first group.
This engineering construction design adoption the frame-shear wall construction. The structure of the vertical longitudinal loading analysis. Concrete contents include: structural programmes and primary cross-sectional size; floor structural design; Structural calculation diagrammatic drawing and stiffness parameter calculation; Structural load calculation and displacement calculation; Level load role of endogenous force structure analysis; Vertical load role of the endogenous force structure analysis; Load effects and endogenous force portfolio; Cross-sectional design and construction requirements; Foundation design; Structural construction mapping; computer-aided design. Earthquake in cross-sectional design, pillar by bias components calculated to ensure extensive framework to \reminder and weak bends, strong column and weak beam, strong joint weak components strong anchorage\design principles, and the cross-section must to meet the demand of construction requirements.
