Development of the Iranian Code for Concrete Design of Buildings is an important achievement that has been made in the recent years. The safety factors and the formula that have been used in this code have been taken from codes of other countries, especially that of CSA A23.3
M84. Since the domestic conditions of
building construction are different from those of other countries, it is necessary to evaluate the safety level of the code for Iranian workshops. In this study, conditions of more than 53 workshops in Tehran and its suburbs have been studied and relevant statistical data including concrete
compressive strength, dimensions of concrete sections, yield strength, location and magnitude of reinforcing bars have been collected. By analyzing the data and doing risk analysis, it has been shown that the safety level for the Iranian code is lower than the assumed value. To reach the desired level of safety, some recommendations are made in this paper as to correct the load and resistance factors.
