Study of various theories for beam revealed that , for beams of small span/depth ratio, shear stresss are high and resulting deflection due to shear can not be neglected. For high L/h results from Euler beam are close to that using Timoshanko beam since the effect of shear deformation on deflection is negligible.

So, beam deflection from my hand calculated results are differing considerably from that obtained from CAESAR=II analysis since in my case the L/D is 10 (which is very less). When the L/D for the same example is increased to 100 or more the results from hand calculations (using Euler beam formula) seem to come much closer to that obtained by use of CAESAR-II(which possibly uses additional correction factor due to shear deformation into account in its element stiffness matrix formulation) .
