| Research Abstract |
Structural performance of damaged SRC beam-columns with open-web type of batten/lattice plate and RC beam-columns after retrofitting was investigated. Nine open-web type of SRC beam-column specimens and six RC beam-column specimens were tested under combined constant axial load and cyclic lateral load. At first, each column was loaded to the targeted displacement. After the first loading, the test columns were retrofitted and reloaded. The damaged portions of each column were retrofitted with the polymer cement mortar, and the resin of epoxy injected into the cracks. All of the retrofitted columns have shown higher load carrying capacity and lower stiffness, while the experienced displacement in each column was different.
