Structural Engineering Made Simple #24 Lateral Load Distribution to Bracings, Frames and Shear Walls
This video is Lesson 24 in my “Structural Engineering Made Simple” series. It presents the procedure for computing the lateral load distribution to lateral load resisting systems such as braced frames, moment frames and shear walls. Lateral loads are those from wind or seismic effects. The video also presents the procedure in computing the rigidity of shear walls, moment and braced frames.

    What a great video, I suscribe. Please keep going, your guidance is just great. By the way, can you please clarify me something? I don't understand why when considering the compressive force in the concrete we don't compute "a" as "c/b1", just like reinforced concrete design? being "b1" = 0.85 according to Whitney theory and "c" the portion of concrete under compressive stresses? Thank you for your time!

    I have a question, we considered Cf = min of (As*Fy & 0.85 f'c*t*b) this means that the full composite action will occur when the section is able to develop its full plastic strength (compact section). Given the web is noncompact, the section strength is already limited to the yielding moment not the plastic moment. So, why do we reduce the transformed elastic modulus.

    this is all good...however....I have seen not design ....of throughout bolts with a backing plate... I have a Simpson strong wall sitting on existing footing...my best option to transfer the loads to foundation is to drive the bolts through the 18"thk. concrete and provide a backing plate.... the Simpson wall is 4" wide with 1"diam. rod....so...the distance to one edge is 2"... I could pour / epoxy new concrete...but...that would not make any difference...there are not edge distance issues on the long side... any suggestion...or...can you address an example for such conditions
