Older version of AISI Standard Specifications for Cold Formed Steel Design used to come with MathCAD Spreadsheet design examples. These were individual spreadsheets for flexure check, compression check, computation of effective section properties, screw strength etc.
I lost my copy of CD and am...
I am reviewing a design calculation for the Excavation Support. The loading diagram used by the designer is in the attached link. This is the standard loading diagram provided by NYC Sewer Design Standards for Non-Watertight conditions. Can anyone tell me how the reaction at the dredge line...
I am trying to perform a hydraulic analysis for a small stream where we are replacing the existing culvert. I need to get the HEC-2 input data to run the HEC-RAS model. Any idea where I can get this from? I tried the FEMA website. But I could not find it. Any help would be highly appreciated.
Hello everyone:
I am trying to design a cantilever sign structure. I have to use a square tube for the column (post) due to some constraints. As you are aware, edge stresses build up at the base of the tubular members. According to membrane theory, the bottom has to be reinforced (stiffened)...
Hi Everyone:
I am trying to find the Ultimate and Yield Strengths of galvanized annealed mild steel wires. I need this to design the support system for suspended ceilings. AISC and other handbooks gives the wire gage sizes only. Any idea where I can find the strengths?
Thanks
I have a HP12x53 embedded in a concrete slab. HP12x53 has a horizontal load. How do I determine the stress distribution in concrete. Can I assume a triangular distribution with the hinge at the top of the slab (ie zero stress at top)?. I know that the hinge forms at certain depth below the...
There was thread that was started regarding the Holographic Presentations and visualizations. I am trying to find the thread, but looks like it has vanished into thin air. Can anyone help me find it?
Can anyone recommend a good reference for design of gusset plates and lug plates? I know that there was an article in AISC Engineering Journal (4th Quarter/1991). But I cannot find it. This provides for a simple procedure without going into a detailed finite element analysis.
Can anyone tell me what the constant "c" is in equation C13-5 of the AASHTO Standard Specifications for Structural Supports for Highway Signs, Luminaires and Traffic Signals?
Basically, this section illustrates the design of drilled shaft foundations, however, the constant...
