Project description

Throughout the project, several existing floor and nonloadbearing wall assemblies have been found to not meet the required fireresistance rating when calculated using MMAH Supplementary Standard SB-2. The same is true for several conditions of individually protected steel beams and columns. Each of these conditions was previously assessed to determine the required additional fire protection measures to achieve the required fire-resistance rating of the assembly or structural element. Each condition was summarized as an individual Engineering Judgement (EJ), previously submitted as an Alternative Solution (21 121575 ALT 00, Mar 31, 2021) and referred to as EJ 1 through 7. This submission is an alternative to previously submitted and approved EJ 1, where SFRM is provided on both sides of the terracotta wall to achieve a 90-minute FRR. The methodology used for this is the same as previously submitted and approved EJ 3, where SFRM was added to existing terracotta walls to achieve a 2-hour RR.
