| Abstract | ||
| In this research, a study of strengthened hinged one-storey frames subjected to four-point loading, both experimentally and numerically, is presented. Three full scale hinged frames with dimensions 2400 mm (span) and 1200 mm (height) are tested in this study. The concrete reinforced frames are strengthened using CFRP sheets at locations of sagging and hogging moments. One specimen is strengthened for shear stress, using external CFRP shear laminates, in addition to sagging and hogging moments locations. A non-linear analysis for the tested hinged frames using ANSYS software package is also presented. The strengthened specimens achieved considerable improvement by increasing both; failure load, especially for the third specimen. The results have been confirmed by the proposed numerical model which revealed other important results concerning the strengthening scheme. | ||
