Opis:
This paper includes the behaviour of RC column, using the steel strength data employed by Rafi et al. (2014). Eccentric short columns are studied for this purpose, both tension and compression controlled sections, are analysed considering the current design practice of Pakistan. Three cross sections were analysed using different steel percentages against load-moment interaction and the strength analyses. Concrete strength is also varied in this analysis. The load moment interaction diagrams were observed in major and minor axes and strength analysis is made for compression controlled and tension controlled sections. In this analysis it is observed that a section designed as a tension controlled is giving brittle failure at certain limit which should be avoided. Considering this scenario, several random cross sections are analysed, strength reduction factors for eccentric and pure axial columns are computed. Conclusions are made on behalf of this analysis for different types of column design.

Opis:
Design codes propose to restrict the nominal probability of failure within specific target structural reliability levels using a load factor and a strength reduction factor. In the current ACI318 Code, the strength reduction factor varies from 0.65 to 0.90, and the value considered in predicting the shear strength equals to 0.75. In this study, the change in the strength reduction factor in predicting the shear strength according to ACI318 has been investigated for different coefficients of variation of concrete compressive strength by using the first-order second moment approach, and the strength reduction factor is proposed for the target values of failure probability.

Opis:
In the design of flexural strength, the strength reduction factor φ decreases from tension- -controlled sections to compression-controlled sections to increase safety with decreasing ductility. This paper presents how to determine the reduction factor for flexural strength of reinforced concrete beams according to ACI code. In the reliability-based design, the reliable prediction of the flexural strength of reinforced concrete members is assured by the use of reduction factors corresponding to different target reliability index β. In this study, for different β and coefficients of variation of the flexural strength parameters, the flexural strength reduction factor has been investigated by using experimental studies available in the literature. In the reliability analysis part of the study, the first-order second moment approach (FOSM) has been used to determine the reduction factor. It has also been assumed that the random variables are statistically independent.
