Plastic Joints in Bridge Columns of Atypical Cross-Sections with Smooth Reinforcement without Seismic Details

In seismically active areas, knowledge of the actual behavior bridges under seismic load is extremely important, as they are crucial elements transport infrastructure. To assess their resistance, it necessary to know key indicators response. Bridges built before adoption standards for detailing may still contain structural reserves due properties used materials and construction approach. For example, smooth reinforcement which found in older material properties, principles, lower bond strength compared ribbed reinforcement, allows greater deformations. bridges, columns vital employed dissipation energy. Their cross-sections often deviate from regular square, rectangular, or round cross-sections, typically building. Based on vicinity potential plastic joints, we can determine deformability. This paper presents an experimental study resistance around a joint column with atypical cross-section, without details reinforcement. The results numerical analytical, but also samples Conclusions made about such indicators, allowing application analytical method realistic element derivation correction factors effect smooth-reinforcement slippage anchorage area.
