【正文】 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.
