Similar to hinged bases in the preceding section,these are framed structures without provision for cranes. /H1L 2S; /H1L 2/H1 S2 /H1IAB IBCQ ;/H1F /H1(1/H 2(1/H; /H1(1/H 1/H1 /H1(3/H; /H1[2/H1/H1A(1/H] Parameters ,,,,,,, and Eare to be used along with Figs. 2A2D. Parameters such as span , height of frame , slope of rafter, Sare to be known for frame. 2.2 Warehouse with Facilities for Cranes These frames have xed bases. The columns have larger cross-section up to the level of the gantry (Fig. . The computational aids suggested are quite general. Some assump-tions, such as axial deformations, are neglected without signicantly affecting the results.Using principles of minimization of energy, the following set of equations may be written: Ga1/H1HGa1/H1VGa1/H1f1() ( /H1MGa2/H1HGa2/H1VGa2/H1f2() ( MGa3/H1HGa3/H1VGa3/H1f3() ( Structural Considerations: Warehouse and Silo 2 Fig. 3 Gable frame with stepped column showing redundance.
