Thank you both for your responses. Eng16080 - I believe it would "cancel", as by adding a post at mid-span to a deflected beam essentially "locks in" the positive bending moment the beam is experiencing under the current loading. By further increasing the loading in the two span condition, you...

Hello All, A quick conceptual question regarding supporting an existing beam and the sequence of loads. For this conceptual question, assume a uniform load over the length of the beam. I have a condition where I have a roof beam that is currently supporting load. A client has asked to add...

SliderRuleEra, thanks for the reply. I am assuming you mean if it is adequately anchored to resist forces as per ASCE 7 chapter 13, correct? In any case, I appreciate the feedback.

DaveAtkins, thank you for the reply. I guess I was not super clear in my last point made. I would be using the 250psf live load as the live load in load combinations. But for seismic weight determination I would be using the usual dead loads added to the true weight of the equipment. I would not...

Good Morning All, Just a quick question regarding how to consider loads from some permanent equipment in a manufacturing facility. I am designing a 2nd floor mezzanine that is to be used to support heavy manufacturing equipment at a load of 250psf per ASCE 7 table 4.3-1. This is fairly...

Hello All, Quick question for you all regarding components and cladding pressures regarding a roof with overhangs. I have been doing a bit of digging and the way ASCE 7 presents the information appears conflicting, or at least misleading. I am speaking of components and cladding figure 30.3-2A...

Thank you once again. I think that is a missing piece of the puzzle that should help me understand this all more.

Thanks, KootK. So this is an area where deflection would be noticeable. So essentially you are saying that if deflection (an the associated lower pressures) are to be avoided, designing to at-rest pressure is the best bet?

Hello All, I am working on a retaining wall structure that is essentially a basement without a floor over the top. So it is a square with strip footings underneath the perimeter, but the top is not restrained by a floor. From how I understand it, active and passive pressures develop when the...

I would like to thank everyone who took the time with explanations and suggestions. Definitely very helpful and very much appreciated.

The beam is only failing on paper as of now, as the structure has not been brought up to the full loading it is expected to see during it's design life. Oddly enough the beam is in negative flexure, so additional self-weight may actually help in counteracting the governing moment...

Good Afternoon All, I have a concrete beam that is failing in bending and was wondering if it was possible to reinforce it by adding an extra layer of concrete and tension reinforcement to the already existing beam. Additionally, I planned to put concrete up the two sides and (1) bar of top...

Hello All. I have an odd situation here and am seeking advice. Any help would be greatly appreciated. I have recently been tasked with designing lateral braces for an existing industrial building that did not include bracing in the original design. From an analysis standpoint the building is...
