Hello,
I am reviewing an existing roof structure for the installation of solar panels. I have the original design drawings from the pre-engineered timber roof truss designer. I have completed by own model of the truss system and have comparable results. Then I adjusted my model for the revised...
I currently work for a multi-disciplinary consulting company and primarily complete the structural design of industrial building, equipment supports and marine structures (I.e wharfs, breakwaters).
I have been offered a Project Manager position with a public agency, with the department primary...
Commentary L – Application of NBC Part 4 of Division B for the Structural Evaluation and Upgrading of Existing Buildings.
I’m wondering how many other Structural Engineers use this section when looking at older buildings. It’s been bouncing around the office lately, with regards to what extend...
I have been tasked with designing a mono-pole structure. The base tube is approximately 1000 mm DIA. and 13 mm plate. I am wondering if anyone has any good references for the design. I have modeled the structure and feel confident with the loading. I’m looking for references on the capacity of...
hello,
I'm a Structural Engineer that has been tasked with designing several steel lattice towers. They are approximately 21m in height.
The towers are in Canada and I will be designing to the Canadian Codes. I'm wondering if anyone has any good references for the design such as articles...
I have modeled a sloped roof with plates. I have noticed that when looking at the stresses, the plates appear to be removing compression force from the top chord of the trusses below. I have selected the "plane Stress" option so the plates shouldn't do this (or that's how I understand it).
I...
Hello,
I have an extremely large industrial building. with purlins running at 2.4 m c/c, continuous over all beams/girders. the purlins are about 12" deep with a metal decking on top.
My question is how can I determine if the purlins are capable of transferring the load to and from the decking...
I'm currently working on a suspension bridge where the main cable will go over the top of the tower, then continue down to the rock anchor foundation, in once continuous piece.
I have previously completed work where cable size was critical compared to sheave diameter (d/D ratio) to ensure...
I have a project where the previously installed metal decking is now under designed for the new roof loading. I am wondering if anyone has encountered this before. I'm looking for a way to increase the moment capacity.
I have a couple thoughts on how it could be done:
-Attach metal bar to the...
I am currently reviewing the adequacy of some OWSJ that were designed under a previous addition of the NBCC. The owner wants to put new HVAC units on the roof. I have completed the initial analysis with the new roof snow loading and the unit loading.
I haven't worked with the cold formed steel...
I currently work for a Canadian Structural Engineering Consultant. We are looking at expanding our modelling software and I'm looking for some opinions with respect to how each program preforms overall and if it uses the Canadian Codes.
We currently use SFrame and are looking at purchasing the...
I have a custom HSS section that is approximately 5' x 10", it is being used to support large overhead doors.
My question is, the section needs to be stiffened at the top where the pulley assembly mounts to the column. How do I determine how far the stiffeners should run below the mounting...
