Thanks
And dont worry, my terrified phobia for heights will instinctively warn me if its not appropriate to climb it.
csd72, thanks for that post as well i'll take extra caution for radition exposure.
From the looks of it i might have to increase my rates for Danger-pay.
Thanks Hokie66
I first have to submit a quotation so i reckon I'll take a bit longer doing the visual inspection, photographing almost all connections. Say 4 hours per Tower.
But also describe the Scope of works should i feel it necessary later on to do a structural analysis check i can charge...
I need to do a visual inspection and report on the structural condition of two towers.
-16m Lattice Mast
-30m Monopole Mast
Does anybody have some kind of inspection checklist template for when inspecting a steel tower, what should i be looking for?
Don't want to spend a day on a tower...
Anyone know how to calculate the load carrying capacity of a corrugated steel arch thats been backfilled, want to replace a broken concrete culvert.
My structure first principles are a bit rusty.
The section properties:
Yield of a plate=250n/mm^2
Plate thickness,t=7mm
Area of...
Thanks ,all valuable remarks. The tower was a charity project and some guy basically build it in his backyard with no design done.
The anlysis program allows for catenary cables and takes the stiffness into account. If a member buckles it removes that member from the structure and anlyses...
I’ve been tasked to do a structural analysis check on an existing guy mast, standing for 12years. A communications company wants to put up extra dishes. Using a frame anlysis programme (PROKON-South Africa), I did a linear analysis first and checked all the members under axial stress, all...
I tend to agree with Rarebug. Our 3D structural analysis program isnt very compatible with AutoCAD 3D, meaning once you have modeled the 3D structure in AutoCAD you cant simply import it into the analysis program and analyse (Finite element analysis) and design. if this was the case i think it...
In our office the structural engineer does most of the bulk drawing of the structure himself in 2D and lets the Draughts person do the finishing touches. We are looking at purchasing the AutoCAD 3D Package but debating wether it is worth it? Should the engineer model the structure and then pass...
This issue was raised earlier for Guy mast cables but can anyone tell me the Modulus of Elasticity and Co-efficient of linear thermal expansion for a galvanized steel stay wire - 7strands x 2.65mm each for Grade 500MPa and Grade 700MPa
