I've got a weird one that i know i could have solved in my university days, but has me scratching my head these days.
I have a column, fully fixed at both ends, very tall (~9metres)
It is subject to near nil compressive forces, or bending forces (no WL2/8 business). but it is very tall...
I'm in the building construction industry.
I was contacted by the QS of a construction company (general contractor) that I have never dealt with before. They were recommended my way from a regular client of mine (specialist subcontractor).
They had a project they were putting a proposal...
I'm involved on a project where there is existing Glass-fibre reinforced cladding panels that are failing. rising up 15 odd levels on a building in the city. size of panels, about 3m x 1m (approx 3.5ft x 9ft)
we will be removing and replacing, the client hoping for something that looks the...
I am regularily engineering claddings (light weight, regularly fastened back to building). low loads (wind governed). sometimes fixed back to concrete superstructure.
The go to historically has been to use 10 or 12 gauge screws with nylon plugs. though in recent years the suppliers of these...
I find myself often explaining to clients about aluminium strengthening methods (tempering, strain hardening, mostly)
im looking but cant find any videos of the processes being carried out. does anybody have any videos to share?
I work in the construction space. historically for exterior applications, i will use stainless steel fasteners (depending on what the application is).
I have a client doing aluminium cladding. we've specified all stainless steel screws, but there are some areas where rivets are desired. in...
Structural engineer here.
I have a project in a moderate/mild climate, coastal area. Fairly sheltered - approx 500m from the shore which is a sheltered harbour. 4km or so from the open/rough sea.
some fairly fancy cladding is specified. zinc cladding panels, fastened with stainless steel...
I am looking to apply a high build acrylic elastomeric resin (essentially, acrylic paint) to bitumen roofing membrane.
wondering what types of primers would be best to encourage good adhesion to the bitumen membrane?
I work in the consulting industry for building construction.
I frequently run into design situations where i need to create airtight, moisture resistant seals between typical construction sealants (modified silicones, urethanes, silicone-urethane hybrids) to bitumen membranes (roofing, decking...
These days clients /project managers often want to run an entire project through a proprietary project management software.
Problem is, there are a dozen of them out there and each one is clunky and annoying in its own way. With 20-30 projects active at a time, most of these systems will send...
Any engineers here with experience scaling from a sole practitioner to an office with employees?
I am currently a one man show, and the money is pretty good. The phone is ringing quite a bit, ive had thoughts of hiring a few young guns and scaling things. But at what point does a company...
How is everyone's outlook for work at the moment?
I'm in building construction,
Most of my projects are continuing for the moment. A couple hotels that I was working on had the brakes put on the project - they are going to build until lock-up only and not complete interior finishing work...
I work at a small specialty structural consulting firm. 2 owners, both early 60s. 3 employees. 2 smart young juniors, and myself, mid 30's. just been offered to take over from one of the owners who wants to retire.
We are in a HCOL area, in a niche business, right now the construction market is...
I am wondering what is standard practice for residential wood frame construction on the US west coast. Are vapor barriers or vapor retarders required? if so, in which areas?
Vapor barriers are always meant to be on the warm side. In Canada and other cold dominated climates, where interior...
I am a structural engineer that is routinely designing aluminum structures (think gates, fences, railings, aluminum screens) that are often in external environments. Sometimes desert conditions, sometimes wet climates, sometimes very near the sea.
Aluminum members typically anodized or powder...
I have been asked to design a brick veneer wall for a project that has:
high winds (~3-4kPa ULS)
high seismic area
high heights - the client wants to install the brick at heights up to 10 stories.
So I have read the prescriptive requirements of the ACI, and I have the design nailed down. The...
Any engineers here practicing in wet rainy climates?
I have designed precast exterior panels that have big teeth on the front, with an airseal at the interior, that make everyone happy.
Now i find myself working on projects lately that involve exterior concrete walls, acting as structural...
On a wood framed single family home I am doing, there is a wood framed chimney flue structure that is to be clad with masonry veneer.
Its a rainscreen application, with
3/4" vertical strapping at 16"OC
wire mesh screen stapled to the strapping
a layer of fabric will be applied (to keep the...
Hi all. A bit of background.
I'm an EIT working for a company that does structural engineering for wood framed houses. As EOR on these projects we get roped into doing a bit of Geo - we aren't experts, but we sign off on bearing capacity if we can be sure of it. I'm in an area that is mostly...
Page 252 of the 2010 wood design manual provides tables for selection of screws for shear.
The tables have sections on screw shear in light gauge steel (20 and 14 ga) as well as 4.76mm (3/16") A36 steel.
A handy addition - though I don't understand how there is a variation for values of N'rNs...
