汕头市金轮大厦2#办公楼

摘 要

本工程为实际应用课题，位于汕头市，该工程为汕头市金轮大厦2#办公楼，横向3跨，中间跨度为3.5m。房屋总高约15m，共4层，建筑场地约46 m *19.5 m。要求采用钢筋混凝土多层框架结构。在正常情况下，本工程的合理设计使用年限为50年，建筑结构的安全等级为二级。建筑结构的安全等级为二级。设防烈度为8度，设计基本地震加速度值为0.20g，工程场地为Ⅱ类。

根据建筑设计和结构承重、抗震方面的要求以及场地地质条件，合理地进行结构选型和结构整体布置，确定各种结构构件的尺寸，选取一榀主要横向结构框架进行结构设计计算，用计算结构力学程序对该榀结构框架进行电算与手算结果进行对比分析；完成楼梯设计和基础设计；用PKPM软件对整栋框架结构进行PKPM电算；绘制出相关建筑和结构施工图。

通过本模拟设计，可使学生综合土木工程专业各课程的知识，了解建筑设计方法，熟悉结构设计与分析过程。

Abstract

This project is the practical application of the subject , located in Shantou City , Shantou wheel that works for office buildings # 2 , 3 transverse cross the middle span of 3.5m. Housing a total height of about 15m, a total of 4 layers, building site about 46 m * 19.5 m. Require the use of reinforced concrete multi-storey frame structure. Under normal circumstances , the rational design of the project life of 50 years , the security level of the building structure is secondary . Security level for the two building structures . Fortification intensity is 8 degrees, the basic design earthquake acceleration is 0.20g, the project site for the Class Ⅱ .

According to architectural design and structural loading , seismic requirements and aspects of the site geological conditions , reasonably structured selection and arrangement of the whole structure , determine the size of the various structural members , select a transverse specimens of major structural framework for structural design calculations , with the calculated structure structural mechanics framework program of the specimens of Computing and hand calculated results were compared ; complete the stair design and basic design ; PKPM software with the entire frame structure PKPM Computing ; mapping out the structure of the building and construction plans .

Through this simulation designed to allow students a comprehensive knowledge of various civil engineering professional courses , understand architectural design approach , familiar with the structural design and analysis process.
