2. MODELING

CHAPTER 2 "MODELLING" 99 ❖ " Member of the Great Rigor Beam " It is a useful automatic data input tool, which is mainly used when simulating basement walls with the command "Convert Beams to Columns" and creating connected column cross-sections. By selecting the button, the field of parameters is automatically filled in for a high stiffness cross- section with zero specific weight, without cross-sectional performance. ❖ " Rigid Offsets " Enter in cm the rigid sections of the beginning and end of the rod respectively. You can enter the "geometric and inertial parameters" of the linear member yourself or let the program calculate them automatically after you select "Cross-section". ❖ " Geometric and inertial parameters ". Α : the area of the cross-section, (in m2) From : the area of the cross-sectional area of the trunk, e.g. in the case of a slab (in m2) Ix, Iy, Iz : secondary moments of inertia with respect to x,y,z axes respectively (in dm4) Asy, Asz : the shear areas of the cross-section along the y and z axes, respectively (in m2) beta : the beta angle (in degrees) E, G : the modulus of elasticity and shear modulus of the material to be used, (in GPa) e : specific gravity of the material (in KN/m3) at : the thermal coefficient Ks : Soil index (in MPA/cm). The field is activated when you select B-3def as membership type.
