Introduction Other Structures (ASCE 7) (ASCE 2010). These buildings are commonly marred with scars after a string of powerful ground excitations. With better understanding of seismic demand on structures and with our recent experiences with large earthquakes near urban centers, the need of seismic retrofitting is well acknowledged. The basic design procedure is described in this section in terms of engineering design methodology, architectural design examples, and design variations. In light of the presented review, it is clear that a successful retrofit strategy requires a full understanding of the expected response mechanisms of the rehabilitated URM structures and how retrofit measures can alter the complete building response. Oct 20, 2014 · The building was constructed so that it was sliced up into bays, allowing researchers to actually test different portions of the building separately and evaluate different retrofit measures. Code for Seismic Design of Buildings is a self-contained document that includes almost all the necessary seismic design requirements for building structures. Subsequently, a retrofit design was developed by reinforcing non-compliant members and validating the retrofit design by means of a non-linear static analysis. The Social Benefits of Sustainable Design The social benefits of sustainable design are related to improvements in the quality of life, health, and well-being. etc. For seismic retrofit of a complex building structure, due to the large number of structural members, an optimum design which ensures the use of the minimum amount of fiber-reinforced polymer to achieve a given level of seismic performance is highly desirable for economic reasons.
