I am performing a NLTH of a masonry building. How do I conduct such analysis in DIANA Fea. I have already provided the time history through time dependent factors by defining either base excitation. What are the analysis steps needed to run it? I have attached the command file I used. The deflections are very small for 0.4g earthquake(1.7mm) but for same earthquake scaled up to 0.5g gives maximum deflection of 45mm for the used analysis. What could be the issue?
Properties of Masonry taken: Youngs modulus : 2703.1 N/mm2
Poisson's Ratio : 0.32
Total Strain crack model with rotating Cracks
Tensile Behavior: Exponential with ft=0.1N/mm2 and Gft = 0.0081 N/mm
Crack bandwidth specification: Rots
Compressive Behavior: Parabolic with fc=2.5N/mm2 and Gfc = 4 N/mm (ductility index taken 1.6)
Reduction model: Vecchio and Collins 1986
