某中學教學樓框架設計計算
摘要:本設計主要進行了結構方案中縱向框架5軸框架的設計。在確定框架布局之后,先進行了層間荷載標準值的計算,接著利用D值法計算水平風荷載的大小,進而求出在水平荷載作用下的結構內力(彎矩 剪力 軸力)。接著計算豎向荷載(恒載和活載)作用下的結構內力。找出最不利的一組或幾組內力組合。選取最安全的結果計算配筋并繪圖,最后進行了基礎的設計。此外還進行了結構方案中樓梯的設計。

Abstract:The purpose of this design is to do the anti-seismic design in the longitudinal of axis 5. When the directions of the determined,firstly the weight of each floor is calculated.Then the wind load in calculated by D 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 frame of the different axis. Then the internal force (bending moment,shearing force and axis 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 Excal 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 protrating the reinforcing drawings of the components.The design of the stairway is also be approached by calculating the internal force.
