As our cities get more crowded, high-rise buildings have become a common sight.

摘要

As our cities get more crowded, high-rise buildings have become a common sight. Often these buildings are covered in a labyrinth of pipes, cables, and other utilities that are crucial for functioning of building services. These appendages are termed as non-structural elements (NSEs) and are attached to the structural elements such as slab, beam, and column. During an earthquake, NSEs may sway and get damaged due to forces induced by ground motions if not secured properly. Any damage to NSEs may disrupt the building services and create blockage which may hinder evacuation. In fact, NSEs may account up to 85% of project cost depending on the type of building. A test project was carried out to evaluate performance of conventional and modular non-structural supports subject to base excitation using shake table. This paper summarizes the finding of the research program and recommends practices that may be adopted to minimize damage to NSEs during earthquake.
