Any body has any freeware or spread sheet for design of base plate as per AISC 13th edition, ASD or LRFD.

The shallow the truss, less longer the members and hence more axial capacity. So apparently no need to strengthen members if we shallow an existing deep truss or O.W.S.J. Probably it is needed when we check it for axial forces from moment, i.e we find out moment at mid span and depending on...

I need to design a square mat footing. It has four concrete pedestals symmitrical arrangement. Any idea how to find maximum moment and shear + other tips on what is needed to be done.

Does anyone have something handy to find out what will be the maximum number of bars in beam as per ACI 318-05. In case. they do not fit in one layer than what are the if and buts for second or higher layer, stirrups requirements and detailing. Thanks.

I am trying to model a truss using SAP2000. I am unable to understand that in output Why Sap can reduce the cross sectional area of double angles. To me the area should be constant But as I enter different spacing for back to back legs, x-area changes.

rho minimum = 0.0018 x hf / ( 2 x d), where hf = height of footing and d is hf-cover. Is this formula ok as per ACI 318-05 for minimum steel to be used in concrete retaining wall footing.

Which code explains the limit for minimum FOS for overturning and sliding of reinforced concrete wall (and under which clause)

If you read at the end of allowable stress combinations, they do not allow for increase in allowable stress. Does this mean we cannot increase soil bearing capacity 33% due to wind or seismic load.

Is it as per ACI detailing standard that the pile cap bottom mesh should be 12 inch high and pile steel should enter into pile cap run vertically 12 inch and than bend over pile cap bottom steel.

In footings many engineers tend to ignore this minimum steel ratio bw x d x 200/fy . Does ACI or any thing relevant confirms this anywhere. Thanks in advance.

Any guideline on design of circular spread footing

Anybody has any freeware or spread sheet for deisgn od circular pile cap for Tanks.

I have existing 24 inch deep steel joist spanning 40 feet. At one end, for about twelve feet I need to reduce the depth to 12 inches. Any ideas.

We have a post tensioned deck bridge. The tendons are in both directions (like two way slab). Can we cut bridge in half for stage construction?

I am looking for some feedback as to which software is good for bridge analysis and design while working in CANADA

I had a #9 bar bend at 90 degree. There were total 56. 4 of them were broken while a Labour tried to move them for adjustment.Any thoughts on that, how concerned u r with the quality of steel or wrokmanship.

When bolt is tensioned, what will be relaxation losses over period of time?

For a common building, windward wall say has 15 psf positive wind pressure and leeward wall has 11 psf negative pressure. In same vicinity if we have just one simple cantilever wall, it will be deisgned for 15+11 = 26 psf wind load?
