    FEM Floor Vibration

    I am currently working through a floor vibration study for a very sensitive imaging type program. I am targeting 1000 mips and there is some pretty significant difference in response for framing members and shells. Since we are working with a full SAP model, it seems logical to me that we should...

    Hi, I have some mat foundation models that I am using SAFE to analyze and design. Loads are exported from ETABS and include X, Y and Z components. I am trying to do a sliding check, and for that I have removed the subgrade spring from the model and I put pins at each of the mat four corners...

    Effective Properties for Stair Tread Diaphragm

    Hello, Working on a vibration study for stair structure. I am wondering if anyone has seen documentation or has any logical methods for determining the effective diaphragm stiffness properties for stair treads. I also want to explore a box type structure, since the fabricator wants to build in...

    Masonry Elevator Shaft Walls

    Hi, How are you designing shaft walls for elevator thrust? I have seen a pier designated at rails in the past. Are you checking analyzing as a beam-column? How do you check deflections? Just using the beam deflection equation based on cracked/uncracked section? I have a relatively tall wall...

    Existing Grout Strength

    Hello, I am having an issue with column base plates showing grout fracturing and chipping out. The contractor used leveling plates to set the grout prior to erecting steel columns. The grout is now showing signs of damage after erection of columns and framing, but even prior to pour slabs. The...

    Hello All, I am studying some mass timber framing systems and I am looking into composite concrete with mass timber, as well as some steel/mass timber hybrids. I am specifically following a "TCC T-Beam" Example by MytiCon which uses the Eurocode "Gamma Method" to account for the screw...

    Flitch Beam Analysis and Design

    Hello Again Folks, Looking for some insight again. I would say I am a good wood designer, but not an expert. This may be a frustrating subject since it pops up often on the threads, but I do not seem to find anything addressing my current issues. I am working on a heavy timber project and...

    Concrete Slab Fold Depression

    Hello, I have seen some discussion in the past on this and it is really something I want to settle. In my experience, slab depressions frequently occur anywhere in a slab and cannot often be supported in a beam like fashion. I like to think that as long as the area of the fold concrete is...

    Connections to Steel Spandrel Beams

    Any insight appreciated. I have a situation where I need to drop some spandrel beams by 4". This is a podium style application, so these beams are supporting bearing walls above. Usually I try to maintain 0.5" deflection of spandrel beams due to interactions with façade systems. That plus...

    RAM Concept - Working with Rebar

    I'm not even sure what to really ask here. I have experience using SAFE to read off rebar demands and detail my drawings. I am currently using Concept for a job and I am really struggling with their reinforcement feature. It seems to place rebar awkwardly and I find areas of short bars or...

    Multi-State PDH

    Hello, New to the PE community (and eng-tips). I am working on applying for my second license. I am wondering if there are any nuances about PDHs. If each state requires a certain amount will they double count? I do not want to get locked into a crazy amount of PDH requirements. I welcome any...
