10D. DIMENSIONING PART 4/4

CHAPTER 10D 'DIMENSIONING' 51 In the case of superlattice 8, it is observed that its failure is characterized as tensile but the axial force is negative (compression). This means that combination 3 whose data are listed is the combination with the worst in-plane check ratio, while obviously the tensile is from another combination. To find out which combination has the worst tensile ratio, we need to add reinforcement to negate the tensile problem in the lintels that require it. It is important to emphasize here that we should always address the tensile and then and with the appearance of the other checks we can move on to other reinforcements if they are required. Tensile strength is given by the option for out-of-plane bending strength about the horizontal axis. After entering the reinforcement data and checking again we get the following results.
