Seismic Response Prediction of Buildings with Base Isolation Using Advanced Soft Computing Approaches

Abstract EN

Modeling response of structures under seismic loads is an important factor in Civil Engineering as it crucially affects the design and management of structures, especially for the high-risk areas.

In this study, novel applications of advanced soft computing techniques are utilized for predicting the behavior of centrically braced frame (CBF) buildings with lead-rubber bearing (LRB) isolation system under ground motion effects.

These techniques include least square support vector machine (LSSVM), wavelet neural networks (WNN), and adaptive neurofuzzy inference system (ANFIS) along with wavelet denoising.

The simulation of a 2D frame model and eight ground motions are considered in this study to evaluate the prediction models.

The comparison results indicate that the least square support vector machine is superior to other techniques in estimating the behavior of smart structures.
