A bridge is a structure built to span physical obstacles such as a body of water, valley, or road, for the purpose of providing passage over the obstacle. As critical transportation junction in the transportation network, bridge controls the traffic capacity of the transportation network. In the past decade, collapse of highway bridges caused by natural hazard and human error occur frequently. There are three main reason of collapse: 1) overloading; 2) construction deficiency; 3) imbalance of the system safety. In this paper, a collapsed bridge in Harbin is studied based on probability. A reliability analysis is conducted to investigate the system safety of the case bridge under combined effect of overloading and construction deficiency. Some suggestions for bridge quality control are proposed.
