Dynamic Response of Ceiling System with Light Steel Furring and Gypsum Board under Severe Earthquake

Abstract:

In order to make sure reliability of ceiling system according to the current code, response acceleration of ceiling suspension points are obtained by seismic model developed by ANSYS/LS-DYNA. Then the FE model of ceiling system according to the current code is also developed in ANSYS/LS-DYNA. The input acceleration is added on ceiling suspension point. The following features are obtained from ceiling system with light steel furring and gypsum board under severe earthquake. These are: 1 Many gypsum boards which are designed according to the current code are failed and drop down，that may result in casualties. 2 The furrings are failed and did not drop down, then may drop for higher peak acceleration. 3 The ceiling system according to the current code is not safe under severe earthquake.
