Hi All,
I am trying to design a base plate with axial load and bending moment. I have different cases of eccentricity: L/6 < e < L/2, L/2 < e < L and e > L.
I found that different references have different methods of designing it:
1) Blodgett uses the assumption of plane section remains...
Hi All,
I am designing the upper support of a semi-gantry crane, with the following details:
1. Total wheel loads along with impact factor = 650 kips
2. The crane length = 135 feet (centerline of upper rail to centerline of lower rail)
3. Height of upper rail = 84 feet from top of pile...
I am designing a slab 180 ft x 51 ft in plan and 8 ft thick. The slab is supported by columns 8 ft x 8 ft (total 8 columns). The columns are 100 ft long and standing on 8 ft mat foundation. On the top slab, there are 4 nos. of 26 ft diameter cutouts. So, I think essentially, the slab is divided...
Hi Guys,
I am trying to design an 8 ft thick table top slab (52 ft x 15 ft rectangular) standing on concrete columns 8 ft x 8 ft. The columns stand on an 8 ft thick mat.
--- The table top slab has 4 circular openings of 26 ft dia each.
--- Very heavy circular drums will sit on anchor bolts...
Hi Guys,
I am trying to analyse and design a steel 3D frame structure 9m wide x 30 m high x 52m long. The transverse frames are at 13m spacing. There are beams at 3 elevations. The end frames along the longitudinal direction are braced at all elevations. The transverse direction wind is...
Guys, inspired by my last thread about designing a tall steel stairway tower, I thought of starting a new thread.
As wind loads on tall structures become very critical, what aspects do engineers look into when they design tall skyscrapers/towers etc. (the commercial ones that we see around) I...
I am designing a steel staircase tower 4m x 6m in plan area and 63m in height, divided into 2.4m high flights. The following are the details of the structure
---- At each landing level, there are 4 steel beams all around.
---- The steel staircase tower is supported on 4 pedestals.
---- I have...
