Seismic Design and Analysis for Urban Viaducts With a Double Deck

摘要

The urban viaducts with a double deck in Shanghai are now under construction. According to the China seismic design code for of urban bridges (Draft 2001), the seismic design and analysis for urban viaducts has been finished by State Key Laboratory for Disaster Reduction of Civil Engineering in Tongji University. The three-level seismic design approach corresponding the performance levels is adopted. The analysis results for different column cross section sizes and different reinforcement ratios were investigated.
