Dear structural engineers, What is your way to design the torsion resistance of concrete section (L, C, T and shaft elevetor)? Thanks

Hi, A constractor ask me if it's possible to not install shelf angles when the masonry veneer (brick) wall exceed 11m (empirical method)? This implies that brick becomes structural in compression. Lateral loads are supported by structural backing made with steel studs. Is it possible to...

Hi, What is the live load you recommend to use when you design an office floor used for record storage? I don't think that 50 lbs/pi2 is adequate. Thanks for your tips!

Considering that PCASlab does not take into account irregular slab, wich software do you use for structural slab analysis? What are the positive and negative points of your choice? Does anywone use VisualDesign for this application? Thanks

Are you familiar with the CSA S304.1-04, the Canadian Standard on Design of masonry structures? Not me. In table 4 (Specified Compressive Strength normal to the bed joint f'm for concrete block masonry), there are values of f'm for mortar type S or N given for different compressive strenght of...

Hi, In masonry design, how partially grouted masonry is taked into account in the design shear wall in bending (strong axis)? Thanks

Hi, When you have beam parallel to joists, there is no lateral support between the columns except the steel deck. Do you use steel deck as effective lateral support to the top flange of the beam? Which equation do you use? Thanks

Hi, 1) What kind of ductility you use in shear wall design and why? Ductile Rd=3.5 or moderately ductile Rd=2.0 or conventional construction Rd=1.5. 2) Which system is the least expensive? Thanks for your help!

Hi, 1)I'm looking for some rules of thumbs and details to use in design of structural slab to prevent shrinkage cracks. 2)What is your best guide on this subject? Thanks for your help!
