As in the case of highway bridges considered previously, live loads on railroad bridges must be placed so that they will cause the most unfavorable eect on the member under consideration. Live loads are loads of varying magnitudes and/or positions caused by the use of the structure. The earthquake loadings magnitude will depend on the buildings mass or weight, dynamic properties, and contrasts in stiffness of adjoining floors, along with the earthquakes length and intensity. hi engr balaram, do you have a sample copy of structural analysis / design computation of a 2-storey residential house? Live loads on floors of buildings are defined by a uniformly distributed load, line load, and a concentrated load, which, however, must not be applied simultaneously.
