Article Preview

The paper is based on the relatively large-span, thin thickness of the arched corrugated metal roof (ACMR) and the fact that the structure would suffer asymmetry swinging within the vertical plane and structure vibration under the effect of the wind and earthquake. A structure strengthening method called the arched corrugated metal roof with ring hoops (ACMRH) is adopted. With SAP2000, a finite element model is established, with type of w666-18m span, rise-span ratio 0.25, 1mm of thickness and condition of fixed support as its research object. The dynamic time history response is analyzed and compared with documents [1]. Result is shown as below. With the same earthquake wave on the structure added, the vertical and horizontal deflection displacement of the most unfavorable point of the arched corrugated metal roof with ring hoops is always less than that of the structure without ring hoops. The maximal decrement is about 28%. This result indicates the arched corrugated metal roof with ring hoops has a better effect on controlling the displacement deformation.
