I am designing a bulk hydrocarbon (petrol, diesel) loading facility for rail wagons (12 per train). In case of spillage there will be a containment basin below track level. Containment basin will be approx 150m x 15m x 1.5m deep. To reduce fire risk and to support the track, the basin will be...
I have a rectangular frame 2500mm x 1000mm made of circular hollow section. The frame is infilled with a strong canvas, blanket-stitched to the frame. Wind applies a load of 1 kN/m2 to the canvas. What is the loading on each frame member?
Consider one wall of a rectangular vacuum chamber(approx 1m x 1m). The wall is thin steel plate welded to the rectangular steel frame(box section).
The pressure applied to the plate is maximum one atmosphere = 101.3 kN/m2
The pressure will produce shear and tensile stresses in the plate.
The...
Consider a house roof designed to maximise useable space - no trusses.
The concrete tiles rest on battens which rest on timber rafters.
The rafters span from eaves to apex and are supported by steel PURLINS at mid span. The rafters are bird mouthed over the purlin and "may" be nailed...
Consider a pitched roof on a house.
The tiles rest on battens which rest on timber rafters.
The rafters span from eaves to apex and are supported by steel PURLINS at mid span. The rafters are bird mouthed over the purlin and "may" be nailed to a timber runner bolted to the top flange...
Consider:
an oil storage tank 30 metres diam. and 14 metres high, full of oil, sitting on a 50mm sand/bitumen cushion, on top of a compacted, crushed stone pad.
The stone pad is retained by a circular ring wall, 30 metres diam and approx 1.5 metres high (0.6 above GL and 0.9 below GL )
I can...
Consider an oil storage tank 30 metres diam. supported on a consolidated stone pad bearing on vibrofloatation stone piles through alluvial sand and silt and gravel.
The vibro piles will be 2.5 metres apart.
The stone pad will be retained by a reinforced concrete ringwall. The ringwall and stone...
I have a large area of steel shuttered, concrete wall in an industrial situation. I need a low cost idea to break up the surface and hide the marks left by the shutter pans. Any ideas?
I am a new entrant to the forum.
I have been puzzling over the following:
Why are loads always applied to the top flange of beams?
Is the capacity lowered if the loads are applied internally to the lower flange?
