摘 要

根据建筑方案图，本工程结构为四层现浇钢筋混凝土多层框架结构，，建筑面积约3911m2。设计使用年限为50年；结构安全等级为二级；抗震设防烈度为7度；设计基本地震加速度值为0.15g，第一组；框架的抗震等级为二级；采用独立基础，地基基础设计等级丙级；建筑室内外高差300mm，室外标高即为现有自然地面标高。

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。

Design of a light plant in Yangzhou

ABSTRACT

According to the construction program plans, the project structure for the four-situ reinforced concrete frame structure. Construction area is about3911m². And design life is 50 years; Structural safety level is two. Seismic intensity is 7 degrees. Basic design earthquake acceleration value is 0.15g. Earthquake grouped is the first group. Site classification is Class Ⅱ. Using an independent foundation. Indoor and outdoor elevation difference is 300mm. Outdoor elevation is existing natural ground elevation.

According to architectural design and structural loading, seismic requirements and site geological conditions, a reasonable structural selection and the overall layout of the structure to determine the dimensions of various structural components, Select a transverse specimens of the main structural framework for structural design calculations. Select a transverse specimens of the main structural framework for structural design calculations. Computational Structural Mechanics program with structural framework of the specimens of Computing and hand-calculated results were compared, complete staircase design and foundation design. PKPM software used throughout the frame structure PKPM Computing. Mapping out the architectural and structural drawings.

Through this simulation designed to allow students' comprehensive knowledge of the various programs in Civil Engineering, understanding approach to building design, familiaring with structural design and analysis process.
