Should we change stiffness modifiers, if a certain shear wall fails. Suppose I have 10X50 shear wall with 0.7 (for f11, f22) and 1 for f12. Now if these shear wall fails in seismic or wind combo for flexure of shear should we change the modifiers to make it pass.

I am new here and I am stuck in a few problems in seismic design of water retaining structures. I am stuck in "effective mass coefficient ε" asked in ACI 350-3-06 Appendex A Step 5, and S1 ans Ss from ACI 350-3-06. it says the "From the applicable seismic ground motion map of ASCE 7-05, Chapter 22, obtain the mapped maximum considered earth-quake spectral response accelerations at short periods and at 1 second (SS and S1, respectively)" but the maps give values for US and I need values for Lahore.

Hello all, 'Difference between Force & Displacement method of building analysis' This has been a topic for my college assignment .And I am going through many literature to understand it.I have even gone through journals which made a comparison between the two cases, following linear analysis for force based and non linear pushover analysis drift comparison for the displacement based approach. I saw one picture somewhere which I have attached here with. During force conventional method of design,the structure has to obey Hooke's law,and For displacement,it can yield as refering to showing ductility(meaning ,it can take further load without failure).I want to write more on this graph,and hopefully I request you to provide more insights regarding this graph.Thankyou
