Abstract
This project is an applied project based on practical engineering. Title: no. 2 teaching building design of a middle school in lianyungang. The proposed project is located at the intersection of xueyuan road and fengwu road in fenghuang new city, lianyungang city. The floor area of this building is 66×13m, with a total floor area of about 4290m2, five floors on the ground and a building height of no more than 20m. Reinforced concrete frame structure is adopted, the safety level of the structure is level 2, the designed service life is 50 years. Seismic fortification intensity of 7 degrees, design basic earthquake acceleration value of 0.10 g, design earthquake group is the third group, site category for Ⅱ classes, design feature period 0.45 s, belong to the common areas of construction can be.
This design carries out the design principle of "practical, safe, economical and beautiful". Based on the local conditions of nanjing, relevant codes such as "building load code" and "building seismic design code" were searched, and preliminary data such as design load and seismic grade were determined. The design of horizontal frame axis 4 in the structural scheme was mainly carried out. According to the provided design materials, I completed the preliminary architectural scheme design and architectural working drawing design, conducted the frame structure calculation, foundation design calculation, component design and node structure design, completed the construction drawing and construction organization design, etc.
Keywords: seismic fortification, frame structure, structural design

1.1工程概况及设计资料
1.1.1工程概况
本课题名称为“连云港某中学新校区2号教学楼设计”,地点位于连云港市凤凰约4290m2。建筑层数地上五层寸66×13m,层高3.6m。
根据建框架结构。
1.1.2 设计资料
1.气象资料
(1)基本风压值0.55kN/m2
(2)基本雪压值0.40kN/m2
2.场地底层
按土层的地质将场地土在勘察深度范分为 8 个工程地质层,分述如下:
①层素填土:灰褐色少量植物根系,均匀性较差,厚度:0.20~0.70m,平均0.36m;层底标高:2.60~3.08m,平均2.95m; 层底埋深:0.20~0.70m,平均0.36m均能差。
