Question

difference between medium and long span structures

Answer 1

the difference between short and long span beam structure is that in the first one we can't neglect the effect of shear in flexure behavior, but for long span beam we can neglect the effect of shear in flexure design. the ratioin to define the short span beam is when L/d<4

noted. L/d >10 is long span beam, can neglect the shear deformability while L/d < 4 is consider as short span beam and must take into consideration about the effect of shear in flexure behaviour....^^
