Not sure what your loads are. 7x wide might be the best option to avoid any steel. Anyway a PSL can work here? Also you stated "contractor wants".... What are his reasons? Is the Architect fine with using 14" leading to step in ceiling or it protruding down?
I'm uncertain about the dry stack approach in this context. In similar situations, I’ve seen the use of dowels installed directly into the footing, and in some cases, the method of support is left to the contractor's means and methods. Another viable option is to pour a narrower footing...
I have typically seen builder block—essentially a type of CMU—used from the footing up to the point where the stone veneer is supported. In most cases, I recommend one of two options: either blocks or a steel angle. However, given the distance of the stone veneer from the structural elements, as...
Has anyone substituted a roof diaphragm design with zip system (insulation side down)? I am being asked to see if R6 zip will work. Doing some research I only found that there are shear capacities for a shearwall application. Would this work in a seismic design category D? Looking for references...
Does anyone know if you need to apply a vehicle impact load to a deck post? I ask this question because I have a home with a garage on the ground level and there is a deck surrounding the perimeter of the structure. I have been trying to find an exemption to this in code, or if it is even necessary.
Hello,
I was wondering if anybody knows how to calculate the design strength of a circular weld? I have a way of doing it quick and dirty, however, I would like to know how to do it.
Does anybody have any good solutions for top mounting a 4x4 wood post guardrail to n existing 8" concrete wall? I have been dancing around different hardware but nothing works for a 200lb point load at the top. I am free to shift the post anywhere on the width of the wall.
@WARose Yes, a MF after a big seismic event. Essentially, there are going to be yielded rebar. Can they be replaced? How do you determine if they are in good shape? I know of assessments found in P58 and ASCE 41. I also know of taking core samples too.
I was looking over some plans for learning purposes and I saw a RFI that said "3/4" aggregate size is acceptable for beams, columns, slab except for use in high rebar and post-tension congested areas like column to post-tensioned beam connection". It then pointed to use 3/8". Why would a 3/8"...
I have been wondering if concrete moment frames, like the special moment frame, are reusable? Can the yielded rebar be replaced or is it just an analysis procedure to deem the structure occupiable? What about mild steel in precast hybrid moment frames? Can they be replaced?
