Abstract:

Prediction of the changes in internal forces developed in high-rise building structures play a vital role in structural element design as well as in dealing with stability of super-structures, especially when subjected to seismic load, earthquake for example. Recently, several methods have been investigated and proposed heading to examine the behaviour of the super-structures. Among the current methods, full scale physical exercise provide accurate results, but it costly and take time to achieve a work done; hence this method is rarely used. Based on the equivalent concept, the use of equivalent physical model has become common, since this method is low-priced and be able to predict the behaviour of actual structural well. The paper is also based on the equivalent hypothesis to assess the effects of geometric scaling model on the changes in internal forces developed in high-rise building structures by conducting a series of numerical computations, in which two main elements of super-structures were taken into accounts such as column and beam ratios between simulated model to that of actual model. The obtained results indicate that there are significant differences in calculated results of smaller numerical models to that of actual ones. Consequently, care must be paid when investigating the behaviour of super-structures via small-scale model, even with numerical or physical manners
