Seismic Analysis on Single-Storey Industrial Buildings with Roof of Saddle Plate in Different Span

Abstract

At present, although the saddle plate is widely used in roof structures of single-storey industrial buildings, the seismic analysis on single-storey industrial buildings with roof of saddle plate in different span is rare. In this paper, we study the structure’s response to the frequent earthquakes and rare earthquakes by ANSYS software. We also discuss the influence on vibration characteristics and the seismic response caused by the change of saddle plate’s span. We draw the conclusion that with the increase of the span, the natural vibration period of the structure, the displacement on the top of columns and the shear force at the bottom of columns increase; but the increase rate decreases with the increase of the span. The conclusions will give a reference to the seismic design of single-storey industrial buildings with saddle plates.
