Many of the populated areas are close to sea. Wind-borne salt can bring chloride to surface of reinforced concrete buildings, causing steel reinforcement corrosion. Moreover, many reinforced concrete buildings in Taiwan have high chloride content, leading to a premature steel reinforcement corrosion in the design life span of the buildings. Steel corrosion causes reduction in steel area and pitting, damage in bond, and expansion and spalling of concrete. It can greatly decrease the seismic capacity of a structure. There are numerous low-rise reinforced concrete buildings in Taiwan, such as common residential street houses. Many of them suffer steel reinforcement corrosion. However, there is no seismic evaluation method that is verified by experimental study for such buildings. This proposed research aims to carry out experimental study on corroded reinforced concrete walls, two-way slabs and beam-column joints. The proposed research is the continuation of the applicant’s previous research supported by National Science Council on experimental study on corroded beams (including on-way slabs) and columns. Results of this research combined with those of the previous research will deliver a complete seismic evaluation method for corroded low-rise reinforced concrete buildings.鋼筋腐蝕耐震行為雙向版梁柱接頭steel reinforcement corrosionseismic behaviorwallstwo-way slabsbeam-column joints低矮鋼筋混凝土建築腐蝕牆版與&#63866;柱接頭構材耐震&#64008;為試驗研究(3/3)
