Behaviors of super-long span prestressed cable-stayed bridge with CFRP cables and UHPC girder

Fang Zhi,Ren Liang,Fan Fenghong

Strategic Study of CAE 2012, Volume 14, Issue 7,   Pages 53-59

Abstract:

To discuss the applicability of carbon fiber reinforced polymer (CFRP) cables and reactive powder concrete (RPC)in super long span cable stayed bridges, taking a 1 008 m cable stayed bridge using steel girder and steel cables as example, a cable stayed bridge with the same span using RPC(reactive powder concrete) as the girder and advanced composite material CFRP (carbon fiber reinforced polymer) as the cable was designed, in which the cable cross section was determined by the principles of equivalent cable strength and the beam cross section was determined considering the stiffness, shear capacity and local stability. Based on the method of finite element analysis, the comparative study of these two structures on their static properties, dynamic properties, stability and wind resistance were carried out. The results show that it is feasible for using RPC as the girder and CFRP as the cable so as to form a highly efficient, durable cable stayed bridge of concrete structure and make its applicable span reach about 1 000 m long.

Pretest analysis of shake table response of a two-span steel girder bridge incorporating accelerated bridge construction connections

Elmira SHOUSHTARI, M. Saiid SAIIDI, Ahmad ITANI, Mohamed A. MOUSTAFA

Frontiers of Structural and Civil Engineering 2020, Volume 14, Issue 1,   Pages 169-184 doi: 10.1007/s11709-019-0590-y

Abstract: This paper presents pretest analysis of a shake table test model of a 0.35-scale, two-span, steel plate girder bridge. The objective of pretest analysis was to obtain an insight on the seismic response of the bridge model during the shake table tests. The bridge included seat type abutments, full-depth precast deck panels, and a two-column bent in which columns were pinned to the footing and integral with superstructure. Six accelerated bridge construction connections were incorporated in the bridge model. An analytical model was developed in OpenSees and was subjected to ten input bi-directional earthquake motions including near-fault and far-field records. The overall seismic response of the bridge was satisfactory for all the earthquake records at 100%, 150%, and 200% design level. All connections and capacity-protected components remained elastic, and the average ductility capacity surpassed the ductility demand even at 200% design level. Using experimental fragility curves developed for RC bridge columns, it was predicted that there was a probability of 45% that columns would undergo the imminent failure in the last run and a probability of 30% for their failure.
