范文编号:TM083 范文字数:15204,页数:96 附CAD图 摘 要 本工程为某学校行政办公楼,建筑面积9743.57m2 ,建筑层数为5层。建筑耐火等级二级,抗震设防烈度六度,结构选型为现浇钢筋混凝土框架结构。计算步骤为选取5轴框架进行计算,荷载计算和截面估算后,用分层法计算出竖向荷载作用下内力,通过D值法求出水平风荷载作用下内力,并对内力进行不利组合,进而选取最不利组合进行截面设计。另外本设计还包含了对楼板、楼梯和连续梁的设计。本工程基础设计采用桩基,柱下大多为单桩承台。 关键词:结构选型 计算步骤 基础设计 A structural design of the school administration building
This project for the Hangzhou Electronics Co., Ltd. through complex building, the building of 9743.57 m2, for the five-storey low-rise building. Fire-resistant construction grade two, six times the intensity of seismic fortification, for the selection of cast-in-place reinforced concrete frame structure. Calculated steps to select the 5-axis framework, the load calculation and cross-section estimate, calculated by using tiered vertical load of internal forces, are obtained through the D value method under wind load level of internal forces, and a negative combination of internal forces, Then select the most disadvantaged section design combination. In addition the design also includes the floor, staircases and continuous beam design. The project design based on a pile, mostly under the column for one caps.
