Description

The purpose of this paper is to calculate the resistance factors for flexural strength and shear strength of prestressed (reinforced) concrete (PC (PRC)) members. Variations of the strength are evaluated by the following three factors ; (1) differences between specimens and actual members, (2) accuracy of equations to estimate, and (3) uncertainty about mechanical properties of materials and scale effects. These three factors as random variables are investigated using available statistical data and methodology of a Monte Carlo srimulation. Results obtained herein show that the factor (2) above has the biggest influence among three factors. Furthermore, resistance factors are calculated by using the results of the variations.
