    Pile Cap Design Software

    Thank you, Mike20793. Does the SAFE check the deep shear per CRSI or conventional ACI shear? I know ACI shear is too conservative for the deep cap. Also I know deep shear per CRSI has much better shear capacity; how about the moment? Do you use conventional beam concept or struct and tie for...

    Pile Cap Design Software

    Not familiar with SAFE, but when I use RAM CONCEPT to model a pile caps supporting shear walls, the piles directly under the wall receives the most portion of the loads. Did you notice the similiar result from SAFE? But when we design a typical pile cap, we normaaly assume pile cap as rigid...

    How to decide a existing plate girder steel yield stress is 36ksi or 50 ksi?

    So far after talking with an couple of XRF analyzer venders, it looks like X-Ray fluorescence testing (one kind of PMI) can't distinguish two alloys of A36 and A529 because XRF is checking chemical composition and these two alloys have ovelapping chemistries. So cut a coupon and test is the...

    How to decide a existing plate girder steel yield stress is 36ksi or 50 ksi?

    I have to check a existing plate girder capacity. How could I decide the steel plate yield stress? I know normally it is A36, but it looks like it does not work for my load and I suspect they are 50ksi plates. Is there any way to test? Thank you.
