摘 要

本工程位于江苏省南京市，是一栋地上四层的教学楼。用以南京市某小学教学使用，该楼只要功能用途包括：学生教室，功能教室，阶梯教室，教师办公室，会议室，阅览室等。该楼总长58.9米，宽15米，主体高14.85米。其中标准层高3.6米，底层高3.75米，顶层高3.9米。

综合考虑结构安全，经济合理等多方面因素，本楼采用框架结构体系，以框架支撑结构的地震和恒活载。楼板厚100 mm，柱截面尺寸400×400 mm。主梁250×600 mm，次梁250×400 mm，混凝土强度等级用C30，填充墙厚度24 0mm。

本工程位于江苏省南京市，抗震设防烈度为7度，设计基本地震加速度为0.1g，建筑抗震设防类别为重点设防类（即乙类），抗震设计分组第一组，建筑物场地类别为Ⅱ类。地基基础设计等级为乙级，考虑安全性、经济性，以及对建筑物的沉降要求，基础采用独立基础。

ABSTRACT

The project is located in Nanjing City, Jiangsu Province, one of four buildings on the ground floor of the teaching building. With the use of a primary school in Nanjing city the building of teaching, as long as the function uses include: students in the classroom, classroom, classroom, teachers, office, meeting room, reading room. The building with a total length of 58.9 meters, 15 meters wide, 14.85 meters high, the main. The standard height of 3.6 meters, the bottom 3.75 meters high, the top 3.9 meters high.
Considering the structure security, economic and other factors, the floor frame structure, the frame supporting structure with earthquake and dead load and live load. Slab thickness of 100 mm, column section size of 400 × 400 mm. The 250 × 600 mm, 250 × 400 mm secondary beam, concrete strength grade C30, wall thickness of 24 0mm.
The project is located in Nanjing City, Jiangsu Province, seismic fortification intensity is 7 degrees , the design of earthquake acceleration to 0.1g, building seismic fortification for the key protection class (i.e. class B), seismic design in group 1, the building site for the class ii. Foundation for design grade B, consider the safety, economy, as well as to the settlement of the building requirements, based on an independent basis.
