The main objective of the proposed project is the development of procedures and tools that could be used for the design of structures for a tolerable level of seismic risk using different type of analysis. The innovative procedure for the design of structures will represent a major step towards scientifically oriented design procedures employing a high level of technology. Risk-based design will make it possible to define the performance objectives for a continuum of the seismic hazard. Experimental results will provide better insight into the variability of the capacity of structural components due to construction practice.
