WebGEOMETRIC STIFFNESS AND P-DELTA EFFECTS 11-5 11.3 P-DELTA ANALYSIS OF BUILDINGS The use of the geometric stiffness matrix is a general approach to include secondary effects in the static and dynamic analysis of all types of structural systems. However, in Civil Structural Engineering it is commonly referred to as P-Delta Analysis … WebP-Delta is a geometrical non-linearity and it give the additional shear forces and bending moment to the structure due the applied force P, whereas P is the load and delta is a lateral deformation. P-Delta is actually only one of many second-order effects The effect of P-Delta is mainly dependent on the applied load and building characteristics

WebDefine a nonlinear static load case that applies the gravity load, and specify that P-delta effects be considered (see Geometric Nonlinearity Parameters for more information). Call this case "GravityPdelta." Define as many linear load cases as needed that all use the stiffness from case GravityPdelta.
