Wa alaikum assalam, 1. Lateral force resisting system (LFRS) is selected primarily based on the seismic zoning (or seismic category) of the area in which a building or structure is to constructed. LFRS selection partially depends upon the preferred material of construction (e.g., Reinforced Concrete, Structural steel, etc) as well. 2. if you don't have load bearing walls in your structure to transfer superstructure ( floor and roof ) loads to the foundation, it is NOT a 'load bearing wall system'. 3. A 'moment resisting system' is the one in which beams and columns are used to transfer the superstructure loads to the foundation. The walls provided in this type of structure are commonly termed as 'infill walls' or non-load bearing walls. HTH Regards.

you can use the uniaxial compressive strength of concrete or rock which ever is smaller. If u want to use the cohesion value u can take the half of compressive strength which is equivalent to cohesion.thanks

Thanks for your informative reply @Yasir Saleem. You are more than welcome to contribute to topics irrespective of their posted dates.

Really very nice gathering. it was my first meeting with all the members but due to our discussions on this forum for the last couple of years, I didn't even feel once for the 3-4 hours meeting that we were meeting for the first time. Thank you all....
