The assessment of seismic performance of existing structures is becoming an important problem in earthquake engineering. Some important ructures are considerably old and, therefore, their strengths and ductilities are less than strength and ductility demands because of changes in codes and design methodologies. Such structures must be strengthened to resist future earthquakes. First, a structur...
Recent research efforts have focused on the development of performance based seismic design methodologies for structures. However, the seismic design rules prescribed in the current Canadian Highway Bridge Design Code (CHBDC) is based largely on force based design principles. Although a set of performance requirements (performance objectives) for different return period earthquake events have b...
CCondnue on reverse side If necessary and identity by block number) Analysis on a regional basis of the NORSAR seismic bulletin data for the three years from April 1972 to March 1975 shows that there has been no significant tf^"/^^J?^^ detectability during this time period. The detectability has been examined using" the least squares ^\^^' ^! least squares incremental method and the °-^h^ e men...
Lifestyle factors, including diet, have long been recognised as potentially important determinants of cancer risk. In addition to the significant role diet plays in affecting body fatness, a risk factor for several cancers, experimental studies have indicated that diet may influence the cancer process in several ways. Prospective studies have shown that dietary patterns characterised by higher ...
according to iranian code of practice for seismic resistant design of buildings standard no. 2800, yazd is located in the place with the medium earthquake hazard [1]. due to the position of yazd with many historical and important buildings, maintaining these traditional heritages is an important task in civil engineering field. on account of these mentioned valuable buildings and region potenti...
