7- Design of two-way slab using DDM - Design Example

‪@engineeringstudio‬ ****************************************************************** Design of two-way slab system using Direct design method DDM ******************************************************************* Example ×××××××××× Design a slab system having 3 panels of 6 m span each in N-S direction and 4 panels of 8 m span in E-W direction, story height of 3.5 m, service live load = 300 kg/m2, superimposed dead load = 350 kg/m2, fc’ = 25 Mpa, fy = 420 Mpa. There is no drop panel or column capital, edge as well as interior beams are present in both direction. Size of columns is 375 x 375 mm. Size of long beam spanning E-W is 375 x 700 mm and size of short beam spanning N-S is 300 x 525 mm. ×××××××××××
