Also, comparative study between the ECP-201(2012) and the current study. It was found that R factor decreases with increasing floor heights. In addition, increasing the non-uniformity of span lengths greatly effects on the value of the R factor. The listed values of R factor in the ECP-201(2012) are conservative values and can be increased ER -
