When designing a diaphragm using the alternative diaphragm method, there are two categories, shear controlled and flexure controlled, I am getting confused on how can I qualify my diaphragm according to those two categories! The definition of the ASCE7-16 is very general! THIS IS FROM THE...

Is there any good reference for a simplified method of seismic design of culverts??

Hi All, I am designing a field topped composite double tee and I have some doubts on how all engineering programs calculates the horizontal shear forces and stresses: For a composite member all commercial programs checks vertical shear for an expected shear crack through the thinnest part of the...

Hi! I am a structural engineer, and I am designing a project in which has a generator at the roof, the EOR has sent me the generator specs, showing a statement that the generator has built in vibration pads, with that information, I can assume that there is no vibration and consequently no...

Dears, for those who asked about the scope of what is called review engineer or plan checker: performing and managing plan reviews for projects. Projects ranging from small residential projects to high-rise hotels and office buildings, institutional occupancies such as hospitals and jails...

SWComposites--Yes, I have a career path, but at my current job, I am working for the US, overseas at my current job (Not physically in the US) The review engineering firm is offering H1B visa that could get me physically in the US, rather than working overseas.

SWC- I work in precast design and I have been offered to be Review Structural Engineer at another firm owned by firmer building official, simply the review engineer checks the structural, mechanical, Architectural aspects of projects to be code compliant, my concern is it will be less practicing...

Hello, I’m a Structural Engineer I work at a design precast specialty engineering firm and I have been offered a job as plan checker?! What is the future for plan checkers!?

Hello, Does it makes sense to choose a lateral resisting system category in each direction? With different R and Cd? If I have non-load bearing precast shear walls in the Y-axis and load bearing precast shear walls in the X-axis, Knowing that non-load bearing precast shear walls have higher...

Thank you all for your helpful input.

Good day, I have a problem justifying the shear diagram in one of the shear walls; The structure consists of shear walls and since the slab qualifies to a rigid diaphragm, a rigid constraints has been assigned to all shear walls joints. Of course the expected shear diagram of each shear wall is...

Good day, I have a problem justifying the shear diagram in one my shear walls; I have modeled my structure that consists of shear walls and since my slab qualifies to a rigid diaphragm, I have assigned rigid constraints to my shear walls joints.

Good day Engineers, For Buildings with SDC B that have vertical irregularity of type 4 (Discontinuous Shear Walls-Having Shear walls supported on beams and columns), Table 12-3-2 in ASCE7-16 refers to section 12.3.3.3 which says that elements supporting discontinuous walls should be designed...

Why do we define the compression only or tension only springs as non-linear springs?

Thank you very much guys, yes I meant it in prestressed concrete.

Hello, Can some one give me a hint on the differnce between web-shear and flexure shear strength?

Can you elaborate please?

Hello, I have a question that may sound trivial! If I modelled a wall in ETABS as a shell thin and applied on shear forces at different levels, and I defined the restraints at the base on the two edges as pin-pin, shouldn't the two reactions at the base be equal? I see a difference in...

Hello, I have a precast connection connecting to different walls, I have a rectangular steel plate works as a bracket, I'm trying to design it, but I can't decide whether, I have to apply the triangular bracket design procedure or not, to my surprise I contacted AISC and they told me that most...
