摘 要

本設(shè)計(jì)為天津市塘沽xx商業(yè)樓2號樓，建筑面積9048.73平方米。本工程為局部七層鋼筋混凝土框架結(jié)構(gòu)，建筑總高度為26.7米，首層高4.2米，二～六層高3.9米。建筑物防火等級為二級，抗震設(shè)防烈度為7度（0.15g）,設(shè)計(jì)地震分組為第一組，抗震等級為三級。
本設(shè)計(jì)主要進(jìn)行了結(jié)構(gòu)方案中框架5軸框架的抗震設(shè)計(jì)。在確定框架布局之后，先進(jìn)行了層間荷載代表值的計(jì)算,接著利用頂點(diǎn)位移法求出自振周期，進(jìn)而按底部剪力法計(jì)算水平地震荷載作用下大小，進(jìn)而求出在水平荷載作用下的結(jié)構(gòu)內(nèi)力（彎矩、剪力、軸力）。接著計(jì)算豎向荷載（恒載及活荷載）作用下的結(jié)構(gòu)內(nèi)力，找出最不利的一組或幾組內(nèi)力組合。選取最安全的結(jié)果計(jì)算配筋并繪出結(jié)構(gòu)圖。此外還進(jìn)行了結(jié)構(gòu)方案中的樓梯設(shè)計(jì)并完成了平臺板，梯段板，平臺梁等構(gòu)件的內(nèi)力和配筋計(jì)算及施工圖繪制。
在我們完成內(nèi)力計(jì)算時(shí)，還采用了PKPM進(jìn)行了驗(yàn)算。
在進(jìn)行截面抗震設(shè)計(jì)時(shí)，遵循“強(qiáng)柱弱梁，強(qiáng)剪弱彎，強(qiáng)節(jié)點(diǎn)強(qiáng)錨固”的設(shè)計(jì)原則。

ABSTRACT

This design is commercial building for Ziyuyuan in Tianjin Tanggu and floor area is 9048.73 square meters. This project is a partial 7 floor reinforced concrete frame structure, the total height of building is 26.7m, the high of first floor storey is 4.2m, and 2～6 floor storey 3.9m, seven storey 3m, the seismic establishes to defend the earthquake intensity as 7 degrees (0.15g), belong to the design anti-earthquake grade is 3-rated.
The purpose of the design is to do the anti-seismic design in the longitudinal frames of axis5. When the directions of the frames is determined, firstly the weight of each floor is calculated .Then the vibrate cycle is calculated by utilizing the peak-displacement method, then making the amount of the horizontal seismic force can be got by way of the bottom-shear force method. The seismic force can be assigned according to the shearing stiffness of the frames of the different axis. Then the internal force (bending moment, shearing force and axial force ) in the structure under the horizontal loads can be easily calculated. After the determination of the internal force under the dead and live loads, the combination of internal force can be made by using the Excel software, whose purpose is to find one or several sets of the most adverse internal force of the wall limbs and the coterminous girders, which will be the basis of protracting the reinforcing drawings of the components. The design of the stairs is also be approached by calculating the internal force and reinforcing such components as landing slab, step board and landing girder whose shop drawings are completed in the end.
Adopted the design software PKPM to carry on checking calculate when our dint inside the completion of compute.
While carrying on cutting a noodles anti-an earthquake a design, the design of “stronger column weaker beam,strong shear weak bend,strong node the strong anchor man be solid ”for follow original.
Keywords :Structural design;Seismic design;Load
