What is the common foundation of a concrete shearwall in a low-rise concrete structure with a bearing wall system? Since most of the lateral load will be resisted by the shearwall, I've noticed that a shallow foundation (wall footing) is not enough, thus requiring a deep foundation. Am I right?
Hello, we are considering adding an additional floor level to an existing building. We are planning to design the new retrofitted structure as a bearing wall system and add shear walls to carry the lateral forces. My question is, how will we consider the existing columns in the model and carry...
Anyone know a good reference book for the vertical and horizontal distribution of seismic loads for structural frames that includes the computation of relative stiffness, center of mass and center of rigidity? Thank you.

Does the increase of 33% on allowable bearing capacity is applicable for both Basic and Alternative ASD Load Combination?
I remember this increase of allowable stress is only applicable to alternative load combination. For soil capacity, it is allowed for both?
I am new to flexible foundation analysis.
My question is when using the subgrade modulus, the pressure gives by the SAFE would be compared to the net/effective bearing pressure provided in the soil report in determining the footing size? or you have to divide it with safety factor?
I'm...
I just noticed that the footing thickness required for length development for hook in tension is sometimes so much higher than the required thickness based from punching shear.
Is this really reasonable?
PCA Notes example problem shows that we need to consider length development in tension...
