摘   要

该建筑物是位于成都的一栋多层框架学生公寓。根据提供的地形图和及功能要求的规定，进行建筑设计。它的占地面积约810m2，建筑面积约4860 m2。建筑物最高高度为19.45m。
此建筑物采用钢筋混凝土框架结构，结构设计是七度设防，设计地震是第一组，场地为Ⅱ类，粗糙度为C类，耐火等级为二级。其设计内容包括结构布置、构件估算、内力分析、构件截面设计和基础设计几部分。采用整体现浇式，建筑整体刚度较好并进行了进行了地震作用、风荷载和竖向荷载的内力分析，采用了多种荷载组合方式。
钢筋混凝土是一种延性材料，为了充分利用这种材料的特性，根据建筑三级抗震的要求，进行梁端弯矩调幅，柱端弯矩调整，剪力调整等计算，同时注意节点的设计，使得建筑的设计达到强柱弱梁，强剪弱弯的要求，增加建筑的延性，以提高建筑的使用性能。
在此次设计中，多层框架结构分析是采用底部剪力法进行地震荷载下的内力分析；采用弯矩二次分配法进行竖向荷载的内力分析，整个结构的设计均依据规范来计算。
在基础的设计中，根据地质勘察报告，并参照勘察结论和建议，本工程地基基础设计等级为丙级，基础持力层选定为粉质黏土层，采用柱下独立基础。

Abstract
This building is located Chengdu a multilayered frame student apartment. According to topographic diagram which provides and function request stipulation, carries on the architectural design. Its area approximately 810m2, floor space approximately 4,860 m2. Building high is 18.9m。
This building uses the reinforced concrete portal frame construction, the structural design is seven garrisons, the design earthquake is the first group, the location is II kind, roughness is C kind, the fireproof rank is two levels. Its design content including the structural arrangement, the component estimate, the plane unit choice, the endogenic force analysis, the component section design and the foundation designs several parts. Used placement ,the construction overall rigidity is better and carries on has carried on the earthquake load, the wind load and the vertical load endogenic force analysis, has selected the many kinds of loads combination method。
The reinforced concrete is one kind of ductility material, in order to fully uses this kind of material the characteristic, according to the building three levels of earthquake resistances requests, carries on the Liang end moment amplitude modulation, the column end moment adjustment, computation and so on shearing force adjustment, simultaneously pays attention to the pitch point the design, causes the building the design to achieve strong column weak Liang, strongly cuts the weak curved request, the increase construction ductility, enhances the construction the operational performance。
   In this design, the multilayer portal frame construction analysis is uses the base shearing force law to carry on under the earthquake load the endogenic force analysis; Uses  base shearing force law to carry on the vertical load the endogenic force analysis, the entire structure design calculates based on the standard。
    in the foundation design, according to the geological prospecting report, and the reference reconnaissance conclusion and the suggestion, this project ground foundation design rank is the third class, the foundation holds the strength level designation to mount the soil layer for the powder nature, uses under the column the independent foundation。
Key words: Frame; Load; Earthquake resistances; Reinforced concrete
