When the support is provided by another structure, modeling it is always tricky. One can define spring ( FIXED BUT KFX xxx KFY xxx KFZ xxx ) supports but estimating the stiffness of the springs is not always easy. If you do not have a realistic estimate…

Polar Moment of inertia (Ix) in Staad is computed by the St. venant principle Ix = (beta)*b*t^3 where, "b" is width and "t" depth and "beta" is the variable coefficient depends on the "b/t". As "b/t" approaches infinity, the "beta" becomes 0.333. So,…

Hi, In AISC 360-05 and 360-10 code, same formula is used to calculate the shear area (AY and AZ). For W14X90 section, Ay is (14.02*0.44 =) 6.1688 sqr. inch and AZ is (2/3*2*14.52*0.71 =)13.7456 sqr. inch. The same value is used for design and reported…
