A Study of Evaluation Model Relating to Building Seismic Damage-Case Study at the Taiwan 921 Earthquake Areas

Abstract:

The purpose of this study is to use binary regression to construct the forecast model about the damage of the buildings in the earthquake disaster, and differentiate the relationship between the breakage and the collapse of the building and the character of the building by coefficients of the model. The Urban Planning Region of Chung-Hsing New Village is 7.0 magnitude earthquake area and the researched subject of this study. The reasons of the building collapses in the earthquake disaster can be induced by relative bibliographies and investigation data of collapses of the buildings in fields in reference units at 921 earthquake time. The model variables are chosen by considering the feasibility of the data which are obtained and investigated in fields. A forecast model about the damage of the middle and lower floor buildings in earthquake disaster is established by logistic regression of binary regression method. The model is through the coefficient test, the expected sign, the test of significance and the precise rate of the model, to understand the significance of the model coefficient and the application to the strategy.
