    Precast/tilt up wall panel conx

    I see a few disscussions regarding Tiltup and precast panel to panel connection here in previous threads. But still want to nail down with experience and suggestions from people on this group. It looks most people prefer designing the panels independently (for overturning/Inplane shear) and say...

    Boat slip Design Ref

    Good resources and suggestions from all of you and thank you for all that. For this, we have marina layout from civil/Arch form and coordinating with dock mfrs.We are mainly focusing on the superstructure(shed),but need the understanding of overall systems as well. Thanks!

    Expansion at Joint indoor/outdoor slab interface

    Dik, The soil under the slab will be select fill- that way I feel a little better. Another question on this detail: As you see the retaining wall at the outside perimeter ( retaining a 3 ft of soil). Any provision for drainage required on the wall? I am seeing 15 mil vapor barrier under the...

    Railing System with Stainless steel

    I did doulbe check on that to confirm it is the Yield Strenght (Fy), and it is yield. The report also has Fu (about 100 ksi) My concern is tracking the product, who and how accurately they do if we use higher yield based on test.And I belief also they won't test every prodcut. This report is...

    Railing System with Stainless steel

    Hello, My question is on design of railing systems with stainless steel. What would be the yield strength (fy) of stainless steel alloy 304, in practice. Railing Supllier says they have been using 50 -60 ksi and has material testing report to verify. It seems quite a high compared to 25-30 ksi...

    Retrofit of Concrete Structure

    That was a good recommendation to follow ASCE 41, thank you to both of you. Looking into ASCE 41, it seems as the right document for seimic retrofiting of an exsisting building and question about R values is not applicable (or say R =1 system). As R =1, now foundation sizes will be larger...
