  7. Abstract:
  8. Most regions in Iran are located on an active plate boundary. Therefore, many parts of the country face a risk of earthquake damage at some point in time. Therefore, anticipating and addressing the consequences of earthquake events in order to minimize loss of life and damage to property is a national issue.There is concern about the ability of a signification fraction of buildings in Iran to withstand earthquake events. The deficiencies in the design and construction of buildings in Iran result in low-quality buildings vulnerable to earthquakes. It is necessary to identify and investigate the parameters that contribute to these deficiencies.Previous research studies indicate that most construction defects are caused by several factors including the lack of suitable specifications, disregarding the building codes, and omitting the standard procedures.
    The objective of this research is to utilize direct observations, experts’ opinion and library studies in order to investigate the construction procedures of common concrete and steel frame buildings and identify the factors affecting the structural performance. This study was conducted in Fars that is one of the most earthquake prone provinces in Iran.As part of this study,the common building construction procedures in Fars were observed and assessed against the theoretical and practical guidelines. The most common defects were identified. Using the Uncertainly Analytic Hierarchy Process (AHP), these defects were ranked according to their effects on strength and durability of the structures.The factors causing these defects were identified and classified based on the rules of project participants that are the main contributors to these defects including structure engineers, observers, employers, owners and contractors.These factors were identified through survey questionnaires. In the end, using experts’ opinion and library studies, several solutions to obliterate or controls these factors causing risks were identified through interviewing with
