Bridge Structures

The durability of coastal area bridge structures is more prominent, first, the understanding of the durability of the concrete is insufficient before, and the corresponding measures has not taken; Second, accelerating deterioration of the reinforced concrete is due to the environment and climate factors. Experience has shown that both home and abroad: Starting from the design, take preventive protection measures is effective means to improve the durability of reinforced concrete bridge,then it can get twice the result with half the effort. Based on the Tangshan Coastal Highway construction, considering of the leve of the engineering environmental and so on, on the basis of the service life of the bridge design, the durability of concrete structure would be studied.

Performance Based Seismic Design

According to the failure characteristics of reinforced concrete bridge columns and the need of performance based seismic design in bridge, reinforced concrete bridge column performance levels, which are categorized into fully operational, temporarily operational, reparably operational, life safe and near collapse levels are established. To relate bridge damage to socio-economic descriptions at the five designated performance levels, qualitative indices are established. Considering field investigations following a seismic event, quantitative indices for the same five designated performance levels are proposed. Based on the statistical data of 154 seismic performance tests of RC bridge columns with circular section subjected to flexural failure, drift ratio limit for the same five designated performance levels are put forward. It can be used to determine displacement of pier top in performance based seismic design.
