OK - first timer here. In interest of full disclosure, I'm an architect, but there was no category for such on joining info, but hope I'm still allowed! A local building inspector is concerned, I think rightly so, about the cables in a cable rail system a developer is using on a building we've designed. The issue is that the bldg code requires limitation of passage of a 4" sphere. The cables will deflect enough to allow passage of that sphere, if pushed hard enough. The code for intermediate rails says they shall be designed to resist a concentrated load of 50# in accordance with Section 4.5.1 of ASCE 7. Havent been able to get a look at that yet. However, I'm thinking that the cables will certainly withstand 50#, but will stretch in doing so. Any help with how ASCE 7 4.5.1 is applied here? Thanks!
