Abstract
Papers delivered at the seminar are presented. They address the following topics: seismic strengthening of old buildings with modern codes; aseismic strengthening of reinforced concrete buildings; repair and retrofit of existing steel building structures; retrofitting bridges to increase their seismic resistance; fire testing of epoxy repaired shear walls; and ways to evaluate the seismic safety of houses. It is concluded that repair and rehabilitation techniques for seismically weak and historical buildings are different; the consequences of these differences may have direct application to the design of new buildings to accommodate future strengthening. It is acknowledged that field inspection of construction and workmanship of construction craftsmen have a major influence on the seismic capabilities of completed buildings. It is recommended that a means to improve the quality of workmanship and inspection be developed.
