Course Objective

The two-day course aims to equip the participants with the necessary technical expertise and software skills for advanced seismic analysis and design of buildings in Malaysia per EC8 (Malaysia National Annex).

Participants are assumed to have basic knowledge of structural dynamics (through short course or workshop) and familiar with ETABS software. The emphasis of the course will thus be on detailed implementation of EC8 design code permitted methods and use of computer software ETABS v2016.

Key concepts in correct and effective modelling of buildings will be demonstrated with focus on Lateral Force Method (static) and Response Spectrum Method (linear dynamics). Advanced analysis methods such as Nonlinear Pushover Analysis, Dynamic Response History Analysis and Performance Based Design will also be discussed. Participants will be guided through hands-on examples for seismic analysis and design of several realistic building examples including multi-towers building and irregular-shape RC buildings.

While the emphasis is on EC8 for Malaysia, the knowledge and skills learned will also be useful for design of overseas projects with seismic requirements.
