Impact of long period ground motions on the design of concrete structures

Viorel Popa
Technical University of Civil Engineering of Bucharest, Romania

Earthquakes generated by intermediate depth sources in soft soil areas generate high displacement demands on structures. There is a significant engineering experience in Bucharest with the design of buildings for long period ground motions. Various challenges on the structural design of concrete buildings are presented in this lecture. The commonly used structural solutions are introduced and the main aspects in their design are explained. A brief discussion is made on the design performance objectives, with emphasis on the damage limitation requirements. Some aspects regarding the protection of the non-structural components are discussed as well. This point of view is based on the lecturer’s engineering experience in seismic design of concrete buildings in Bucharest.
