In the architecture design parts, the relationships between function and form、building and site are considered in the scheme design. Designs of plan 、front elevation、section plane are pleted in architecture design phase, details of decoration and conformation are also determined in this purpose of the design is to do the design in the longitudinal frames of axis 3. When the directions of the frames is determined, firstly the weight is calculated ,then the vibrate cycle is calculated by utilizing the peakdisplacement method, making the amount of the horizontal seismic force can be got by way of the bottomshear 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 bination 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 ponents. The design of the stairs is also be approached by calculating the internal force and reinforcing such ponents as landing slab, step board and landing girder whose shop drawings are pleted in the end.Keywords:frames。結(jié)構(gòu)設(shè)計部分選擇結(jié)構(gòu)方案中3軸橫向框架進(jìn)行設(shè)計。(論文)題目:長安區(qū)科技局辦公樓設(shè)計長安區(qū)科技局辦公樓設(shè)計摘要該畢業(yè)設(shè)計題目是《長安區(qū)科技局辦公樓》,建筑面積4500m2左右,共5層:。在確定框架布局之后,先進(jìn)行了重力荷載代表值的計算,接著利用頂點位移法求出自震周期,按底部剪力法計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)。 building design;structural design;antiseismic design目錄摘要 iAbstract
