EQUIVALENT ROTATION BEND SHEAR TYPE VIBRATION MODEL GENERATING SYSTEM

摘要

PURPOSE: To accurately reproduce the vibration feature of a complex building with a simple molded of system of material points. ;CONSTITUTION: This equivalent rotation bend shear type vibration model generating system integrating the skeletons of a building in layer units for a dynamic study is provided with a calculating means 2 integrally calculating the rotating springs of beam members for each floor from the energy by the bending and shearing of the beam members, a calculating means 3 calculating the bending rigidity of layers from the work in the vertical direction of the members, a calculating means 4 calculating the rigidity by the bending of individual members from the bending energy of pillar members, and a shearing rigidity calculating means 5 of the pillar members subtracting the bending deformation from the whole deformation and calculating the rigidity by the shearing of individual members. The structural data of the building and the data of the stress analysis result when the horizontal load is applied are read out, and the vibration model of system of material points having three degrees of freedom per layer is generated.;COPYRIGHT: (C)1995,JPO
