Performance Based Design is a logical design process to determine the performance of such structures where normal code-based prescriptive methods may not apply. Although Non-Linear Time History Analysis has proven to be the most appropriate and reliable approach to follow, it requires considerable effort, cost and skill, which may be either not practical or justified in many cases. For such cases, Non-linear Static Pushover Analysis has become a popular “tool” for PBD. However, NSPA has an inherent deficiency that its invariant load distribution cannot take the higher-mode effect into consideration which may have significant effects in structure, especially mid- to high-rise buildings. Several attempts had been made to develop NSPA so that the higher- mode effects can be considered. This paper investigates the effectiveness of several enhanced pushover methods in predicting the response of structures in comparison with NLTHA solution. |
