What is P-delta , P-Delta effects and P-Delta analysis parameters 1

What is P-delta , P-Delta effects and P-Delta analysis parameters

P-Delta effect P-Delta effect, also known as geometric nonlinearity, involves the equilibrium and compatibility relationships of a structural system loaded about its deflected configuration. Of particular concern is the application of gravity load on laterally displaced multi-story building structures. This condition magnifies story drift and certain mechanical behaviors while reducing deformation capacity. P-Delta effect typically […]

Stiffness Irregularity Check (Soft Story and Extreme Soft Story check) as per ASCE 7-16

what is structural irregularity:During an earthquake, failure of structure starts at points of weakness. This weakness arises due to discontinuity in mass, stiffness and geometry of structure. The structures having the discontinuity are termed as irregular structures. Stiffness – Soft Story Irregularity: It is defined to exist where there is a story in which the
