摘  要

本项目为博才中学教学楼,为毕业设计项目。该项目主要用于学校教学,主要包括教室、阅览室、会议室等教学用房。

本项目占地面积902.98m2,建筑面积3611.92m2。项目主体四层,层高均为3.9m,室内外高差为0.45m。建筑总长度为58.78m,设有两道抗震缝,其宽度为100mm。建筑设计使用年限为50年,建筑物的耐火等级为三级。

该建筑结构形式为现浇钢筋混凝土框架结构,框架柱混凝土强度等级为C30,柱截面为500 500 mm2,框架梁混凝土强度等级为C30,纵向框架梁截面为300 700 mm2,横向框架梁截面为300 600 mm2。女儿墙用混凝土现浇,墙体均采用空心砖砌筑。建筑地点地质条件良好,采用柱下独立基础,基础埋深为1.8m,混凝土强度等级为C30。经济符合要求。

设计严格遵守我国现行规范,计算中包括地震荷载计算,风荷载计算,内力组合,框架梁设计,框架柱设计,基础设计,楼板设计,楼梯设计。

Abstract


    The project is a teaching building, which belongs to a graduation project. The project is used for teaching for school, and it contains classrooms, laboratories, offices and so on.

    This project covers an area of 902.98 square meters, and the floor space are 3611.92 square meters. The building is fore stories high . and the difference of height between indoors and outside is 0.45m. The total length of the building is 58.78 m, and there are two avoiding shaking seams which are 100mm wide during it. The designed service life of the Architecture is fifty years, and the construction fire protection rank is three rank.

    The structural form of the civil engineering is reinforcement concrete casting frame .The strength class of the frame column is C30, and the cross sections of column is 500 500 square meters. The strength class of the frame beam is C25, the cross sections of the vertical beam is 300 700 square meters and the cross sections of the later beam is 300 600 square meters . The daughter wall is builded by reinforced concrete, and the other wall is used hollow bricks. The soil condition of the building site is good, so use under column independent foundation with the concrete of C30, and the depth of the foundation is 1.8m. The design meet economy needs.

    The design strictly complied with the currently used code of our Country. The calculation includes the calculation of the earthquake load and wind load, the composition of internal force, the design of frame beam and column, the design of the foundation and the calculation of the stairs , boards and rain loose.
