土建办公楼毕设论文.doc

聊城大学本科毕业设计  PAGE 2 摘 要 该建筑为办公楼，采用钢筋混凝土框架结构。建筑总高为18.3m，共5层，一层层高为3.9m，其他各层层高为3.6m。建筑面积5363.1㎡。 本设计包括建筑设计、结构设计和基础设计。 建筑部分：根据建筑的地理位置，所有的功能分区等设计依据进行平面布置、立面、剖面等方面的建筑设计，力求建筑物的实用、经济、美观。 结构部分：结构形式为框架结构，所有的梁、柱及板均采用现浇，基础采用柱下独立基础，绘出结构施工图。 本设计主要进行了一榀框架的计算。在确定框架布局之后，先计算了恒载、活载、风载的等效荷载以及各杆端的内力，然后用分层法进行内力分配，然后各层叠加，进而求出在水平荷载作用下的结构内力（弯矩、剪力、轴力）。接着内力组合找出最不利的一组或几组内力组合，选取最不利组合计算配筋并绘图。此外还进行了楼梯和基础的设计，完成了平台板、梯段板、平台梁等构件的内力和配筋计算。 关键词：框架结构；钢筋混凝土；内力计算 Abstract The building for office buildings, with reinforced concrete frame structure. Building a total height is 18.3m, a total of 5 layers, each layer of high3.6m. Construction area of 5363.1 square meters. The design includes architectural design, structure design and foundatiom. Design.Architecture: building according to the geographical position, all the functional layout design based on plane layout, elevation, section and other aspects of the building design, and strive to building practical, economic, beautiful. Structure : structure for the frame structure, all of the beams, columns and plates were using cast-in-place, the foundation of the foundation under column, draw the structure construction drawing. The design of the main framework for the calculation of a Pin. In determining the framework for the layout, the first calculation of the dead load, live load, wind load is equivalent to the rod end load and internal forces, and then layering the internal force distribution, and then superimposed layers, and then calculate the horizontal loads Internal force (bending moment, shear, axial force). Then find the most unfavorable combination of internal forces of a group or several groups of internal force combination, select the most unfavorable combination of computing and graphics reinforcement. In addition, the basis for the design of the stairs and to complete the platform board, bench plate, platform and other components of the internal forces and beam reinforcement calculation.
