Microsoft Word - Flexural Beams -5STRUCTURAL STEEL DESIGN )composite BeamsNon( DESIGN FOR SERVICEABILITY In addition to designing for bending and shear , beams also need to be checked for serviceability .There are two main serviceability requirements :deflection and floor vibrations .Excessive deflections will often lead to vibration problems . The basic deflection limit are summarized in Table below .Note that only service level loads are used for serviceability considerations . In design situation, it is common to develop approximate deflection equations in order to allow for quicker selection of a member based on deflection limitations. The deflection for a uniformly loaded , simple-span beam is : 5 384 8 Faculty of Engineering Al-Mustansirya University
