Hello Everyone.
I was asked to verify a design of a roof structure. Everything was fine till I started to check the braces. It was used a X bracing model and the bars where considered as tension only. But the profiles used where 3" starred angles (very common on industrial sites over here). For...
Good morning, Everyone.
I am trying to understand buckling factor analysis results. I've made this 11m truss and considered both top and bottom chords will be conected to a column. I have considered translation in all directions as fixed and rotation in the x axis restricted too. My analysis is...
Hello, everyone!
I am designing an endplate to be anchored on a concrete reinforced column with chemichal anchors. I am evaluating shear on the direction shown in attached picture (column height direction).
I have two analysis situation
(Situation 1)
According to ACI 318 for shear parallel to...
Hello fellow engineers. I am working on a big structure that at some point will have a truss beam connecting in the web of other beam that is transversal to it. Since I am working with a 3d analysis I am a little confuse on how to model this situation on the software. I've attached 3 pictures to...
Hello fellow Engineers.
I was asked to review a free standing crane runway girder for a 20t crane. Due to space limitations the project was made with beam span of 14m and column height is 9m.
I did check the runway beam (simply supported) and the columns according to design guide 7 and in...
I am starting to study composite beams and I have some doubts on this subject.
First, from my understandment, as long as I am only working with positive moments I can consider both primary and secondary beam as composite beam. If I am working with moment frame beams I should ignore composite...
