¹Table provides the mean strength of blocks (f_uc). To get normalized block strengths (f_b), these values are multiplied by shape factor as shown in equation (6). ²Table provides the mean strength of masonry wallet (f_mc). To get normalized masonry strengths (f_m), these values are multiplied by h/t ratio correction factors as shown in equation (7). ³Values provided are wet compressive strengths. However, same block type used in Venkatarama Reddy et al.[29] and dry compressive strength obtained from that before calculated the normalized compressive strength.
