Structural and Architectural Design of Complex-Shaped Structures in Seismic Regions: Early Stages from a Practical Perspective

摘要

This paper attempts to fill the knowledge gap that is encountered in the structural and architecturalrndesign of complex-shaped buildings in seismic prone regions. In a combined effort betweenrnacademia and practice the challenges involved in the seismic design of complex geometry structuresrnhave been analyzed through a number of complex-shaped case study structures. Several parametricrnstudies on the seismic performance of typical complex geometry components have been performedrnfor the design situation where the complex geometry does contribute to the lateral stability. In therncase it doesn’t, the principles of a previously proposed innovative design solution are shown thatrninvolves the isolation of external irregular parts of the structure from the regular interior one. Thernfindings have been formulated as generic design recommendations, aiming to aid the early stages ofrncomparable designs.
