Tóm tắt

Realising that acceptance criteria for the compressive strength of concrete is important for achieving safety and economy in construction, IS 456:2000, has recommended suitable criteria. The criteria recommended in IS 456:2000 are based on statistical sampling theory. However, the risk associated with the acceptance criteria is not known. In this work, an attempt has been made to examine the acceptance criteria for the compressive strength of concrete specified in IS 456:2000 through statistical sampling theory in conjunction with Monte Carlo simulation technique. From the results obtained, it is noted that the risk associated with the acceptance criteria for the compressive strength of concrete specified in IS 456:2000 depends on the standard deviation of compressive strength. Based on this observation, a method has been presented to achieve uniform value of producer’s risk through the use of a factor.
