内容摘要

本文为某高校研究生院办公楼的结构设计计算书。该楼位于大连市某地，建筑面积约为6000m²左右，抗震设防烈度为七度，抗震等级按三级计算。本设计主要进行了结构方案中横向框架2、3、7、8轴框架的抗震设计。在确定框架布局之后，先进行了层间荷载代表值的计算,接着利用顶点位移法求出自震周期，进而按底部剪力法计算水平地震荷载作用下大小，进而求出在水平荷载作用下的结构内力（弯矩、剪力、轴力）。本设计只选取一榀主框架进行设计计算，首先计算竖向荷载（恒载及活荷载）作用下的结构内力（在内力计算中，恒荷载、活荷载和雪荷载用弯矩二次分配法进行计算），目的是找出最不利的一组或几组内力组合。 选取最安全的结果计算配筋并绘图。此外还进行了结构方案中的室内楼梯的设计。完成了平台板，梯段板，平台梁等构件的内力和配筋计算及施工图绘制。同时对标准层楼板、柱下独立基础以及联合基础进行了配筋计算。最后，依据计算结果，结合相应的结构构造要求，绘制结构施工图，写出相应的设计说明。本计算书所有项目均以最新规范规定为依据。

Abstract

   The text is the calculation book of structure designing of the building for the graduate student hospital in the some high school.The building locates the certain place of Dalian City and the area ratio of the constrction is about 6000 m². Anti-seismic earthquake intensity is seven degrees, and anti-seismic grade is three grades. The purpose of the design is to do the anti-seismic design in the longitudinal frames of axis 2、3、7、8. When the directions of the frames is determined, firstly the weight of each floor is calculated .Then the vibrate cycle is calculated by utilizing thepeak-displacement method, then making the amount of the horizontal seismic force can be got by way of the bottom-shear force method. The seismic force can be assigned according to the shearing stiffness of the frames of the different axis. Then the internal force (bending moment, shearing force and axial force) in the structure under the horizontal loads can be easily calculated. This design selects by examinations only a the main frame of carries on the design calculation. After the determination of the internal force under the dead and live loads, the combination of internal force can be made by using the Excel software, whose purpose is to find one or several sets of the most adverse internal force of the wall limbs and the coterminous girders, which will be the basis of protracting the reinforcing drawings of the components( In inside the dint calculation, the lotus of  carry, lives the lotus to carry to carry to use the curved  to assign the method to carry on the calculation two times with snow lotus). The design of the stairs is also be approached by calculating the internal force and reinforcing such components as landing slab, step board and landing girder whose shop drawings are completed in the end. At the same time to standard floor plank, pillar next the independent foundation and the composite beam foundation carried on to go together with the calculation of reinforcing bar. Finally, according to the calculation result, and combine with the homologous structure request, drawing the structure construction diagram, write a design elucidation for correspond.All items of this calculation book all designate as the basis with the latest norm.
