xx市康科综合楼设计

1绪论

xx市康科综合楼位于光明大街以东，北邻联纺路，紧临高新技术开发区，是集宿舍、办公、娱乐、餐饮、会议等功能为一体的综合性建筑物，总面积5000m2，总高度24.3m，局部高度21.9m。在设计中力图达到功能配置合理性，形象清新脱俗，造型个性突出，与其它建筑物和谐统一，为城市面貌增色。本工程设计单位为康科科技公司，工程为一综合办公中心，包括服务营业大厅、办公用房、会议室及辅助用房、车库、娱乐用房等。

1.1 气象条件

室外气温：年平均温度最冷月平均-2℃，年平均温度最热月平均33℃，冻土深度0.5 m。 主导风向：夏季南风，冬季北风，最大风速19m/s。 土壤冻土深度：-0.6m。 基本雪压：So=0.35KN/㎡。 基本风压：Wo=0.30KN/㎡。

1.2 工程地质情况

第一层：杂填土，层厚 1.5～2.5m。

第二层：粉土，层厚2.7～3.5m，承载力特征值fak=130kpa。 第三层：粉土，层厚2.7～3.9m，承载力特征值fak=105kpa。 第四层：粉土，层厚1.0～2.0m，承载力特征值fak=140kpa。 第五层：粉质粘土,层厚1.5～2.5m，承载力特征值fak=105kpa。 第六层：粉质粘土，本层未钻穿，承载力特征值fak=200kpa。

基础持力层为地三层粉土层，其承载力特征值为105kpa，根据地质报告，边坡临界直立高度Hcr=3.8m。

场地地势平坦。

1.3 地震烈度

(1)地震效应根据全国地震区划分图，抗震设防烈度为7度，设计基本加速度值为0.15g，设计地震分组为第一组。

(2)建筑场地类别为Ⅲ类。

1.4 建筑物的组成及功能要求

本工程建筑面积约6000平方米左右，主体7层，,结构形式为框架结构。 建筑的基本要求：

 一层为服务营业大厅，部分辅助用房等。

 二、三、四为办公用房。参考面积：大办公室35㎡，小办公室20㎡。  五层为宿舍（不带卫生间）。  六层为多功能厅和会议室。  七层为餐厅。

各层参考层高：首层3.9～4.5m，标准层3.0～3.6m，六层:3.9～4.5m. 其他要求：

本工程建筑耐火等级为二级，建筑耐久年限为二级，屋面防水等级为Ⅲ级，防水层耐用年限为10年。设备条件的电力、供水、排水、供热均由城市系统引入。

1.5 建筑设计的内容

根据该房屋的使用功能及建筑设计的要求，进行了建筑平面、立面及剖面设计，其标准层建筑平为面、结构平面和剖面示意图分别见图1.1,1.2和1.3。主体结构共8层，首层层高4.2m，标准层层高为3.3m。
