Shear & Bending Moment Diagrams: 7 Shear And Bending Moment Q&A Shear & Bending Moment Diagrams: 7 Shear And Bending Moment Q&A - Full Transcription So looking at some questions that have appeared on the ARE before, it's basically word questions that have appeared,
Lateral Stability
Shear Walls: 4 Sw Discussion Shear Walls: 4 Sw Discussion - Full Transcription So the last lateral system I would like to discuss is the shear wall. The post and beam we said is totally useless in the lateral direction. The moment frame has rigid connections between horizontal and verticals,

Moment Frames: Bent Moment Frames: Bent - Full Transcription In this video I'd like to talk about rigid frames or bends, rigid bends, that are these pieces here, these red pieces that are laid out at a certain spacing, a certain distance between each other, that are very
Lateral Stability
Moment Frames: 2c Mf Math Moment Frames: 2c Mf Math - Full Transcription So let's look at a moment frame instead, and let's look only at a lateral load. And let's remember the difference between a brace frame and a moment frame is the
Lateral Stability
Moment Frames: 2b Mf Discussion Moment Frames: 2b Mf Discussion - Full Transcription So examining the moment frame and hopefully you've seen in the toys video, I would like to do two things in this video. One is to explain the deformed shape of the moment frame that

Moment Frames: 2a Toys Moment Frames Moment Frames: 2a Toys Moment Frames - Full Transcription Now what happens if we rigidly attach the horizontal to the two verticals? This is called a frame when you have rigid connections between horizontal and vertical. So it's no more a post

Masonry: Truss And Ladder Masonry Ties Masonry: Truss And Ladder Masonry Ties - Full Transcription So the horizontal reinforcing in CMU and brick, it either comes in the form of a truss tie or a ladder tie. So here's a truss tie. It looks like this. It looks

Diaphragms: 3. Rigid Diaphragms 2 Diaphragms: 3. Rigid Diaphragms 2 - Full Transcription Okay, so let's do some of the math on rigid diaphragms. And we said previously that if the diaphragm, sorry, if the collectors deflect more than twice the diaphragm deflection, then we have a rigid
Lateral Stability
Diaphragms: 3. Rigid Diaphragms 1 Diaphragms: 3. Rigid Diaphragms 1 - Full Transcription So we talked about flexible diaphragms, and now I'd like to get into rigid diaphragms. And here we had an example earlier of a flexible diaphragm made of regular plywood or OSB on top of
Lateral Stability
Diaphragms: 2. Flexible Diaphragms Diaphragms: 2. Flexible Diaphragms - Full Transcription So summarizing what we saw in the introductory video on diaphragms, some terminology, collectors are basically your vertical lateral resisting system. So if you have partition walls, of course, those don't count as collectors, but a brace

Braced Frames: Toys Cbf Ebf 2pin 3 Pin Braced Frames: Toys Cbf Ebf 2pin 3 Pin - Full Transcription Okay, so the tension-only bracing cannot handle any compression, and so if the load, the lateral load, puts the diagonal into compression, it buckles, and we said one of the remedies
