PURPOSE: To provide an apparatus wherein an analysis of the state of dynamic response due to a wind external force applied in all directions is executed for an analytical model being similar to a building model provided for a wind tunnel experiment and also the state of the dynamic response due to the wind external force is analyzed for the analytical model being similar to the building model once provided for the experiment, without conducting the wind tunnel experiment afresh. ;CONSTITUTION: A directional wind pressure coefficient at each observing point level is determined on the basis of a normal direction wind pressure coefficient in each time history at each observing point level of a building model determined by a wind tunnel experiment, and it is stored in a data storage means. Then, the directional wind pressure coefficient read out is corrected to a height level of an analytical model being similar to the model, a wind external force is calculated from the directional wind pressure coefficient thus corrected, the dynamic response displacement, etc., of the analytical model and the axial force, etc., of a member are calculated by inputting the wind external force, and maximum values thereof are determined.;COPYRIGHT: (C)1994,JPO&Japio
