I practiced in the british isles for 10 years and in vertical walls, we always just scabbled (exposed the aggregates) at the joint carried the rebar through and assumed it has the same shear capacity as a monolithic joint.
I practice in N America (Canada) now and they always cast a shear key in...
I'm preparing for the IStructE Chartered member examination in January. I'm looking for a very "quick and dirty" way of estimating the sway deflection under wind load in a steel building moment frame. Typical building bay width is 6 to 8 m and storey height 3 to 4 m. Could be any number of bays...
Hi There,
I am researching how to determine the axial capacity of open ended tubular piles in primarily cohesive material. The methods I have read about say you should check the plugged and unplugged conditions.
1. The plugged capacity = Outer skin resistance + Base resistance of a closed...
Attached is a picture of a grouted baseplate. Our site rep is telling me the edges of the grout (microsil) are crumbling and have a honeycombed appearance. It can be broken up in your hand quite easily. Any ideas about what happened? I don't know if the strength has been compromised or...
Hi -- I'm looking at a footing and checking overturning. Criteria as follows:-
1) Uplift = 200 kN
2) Shear = 100 kN
3) Weight Soil Backfill = 200 kN
4) Depth = 2 m
5) Width = 2m
Refer to sketch attached.
Question: Is the footing stable in overturning or not? Assume that loads are un factored...
We are designing a 9 storey steel industrial building supporting mechanical equipment. There is a designated area where 5/6 people work 5 days over 40 hrs per week. The building is cladded.
What category does it fit into, building or non building similar to a building? Problem is, if we design...
