摘要本工程为西安某学院办公楼设计，该楼为六层，总高23.3米，总建筑面积约为6287.76m2。
本设计依据设计任务书，运用力学钢筋混凝土、结构力学基本原理及土力学和对材料性质的深刻了解，遵守设计规则，保证建筑结构合理，所有材料的质量和强度合格，工艺良好。
本建筑设计分为：建筑设计、结构设计。
建筑设计采取积极措施来增强建筑物的外表强度和坚固性，给人以心理上的安全感。
另外，还要有艺术的美感，要有时代气息。
结构体系是钢筋混凝土框架结构，结构设计是使结构物得到足够的强度、刚度和韧性的过程。
结构体系选择后，进行荷载分析和强度分析，同时考虑与建筑经济学的关系，把材料制做安装所需成本、所用时间，以及结构使用期间的维修联系起来。
关键词：框架；结构设计；内力计算The Office of the Xi’an XX collegeAbstractThis project is The Design of the Office of the Xi’an XX college, There are six storys in the building.The general is based on the design requirements, original information, application of mechanics RC, basic principles of structural mechanic, soil mechanics and well knowing material quality, obeying rules of design, ensuring the structures of architecture reasonable, and the quality and intensity of all materials are qualified, and the techniques are the same.This architecture design is divided into three parts: architecture design, structural design.Architecture design will adopt available measures to increase constructions’ surface intensity and firmness. It will also give people safe felling on psychological. On the other is a process of makingconstruction structures get enough intensity, stiffness and toughness.After structural system is chosen, carrying out the analysis of load and intensity, at mean time taking into account the associated relation withbuilding economics, combining the time and cost of materials fabricating and fixing, and the maintenance of structure during operation and use period.Construction organization schedule: according to scientific subdivision works, continuous construction methods, reasonable arranging construction orders, paying attention to safe measures, andensure to obtain economic benefit.Keywords : frames; structural design; intevnalforce calculation目录1.1
