Flat Slab Direct Design Method Pdf Bending Structural Engineering For this purpose a detailed research study has been carried out to see the design comparison of a slab system by these two methods given by aci 318 05 code. A slab system can be analyzed and designed by any procedure satisfying equilibrium and geometric compatibility. three established methods are widely used. the requirements for two of them are described in detail in csa a23.3 14 clasues (13.8 and 13.9) for regular two way slab systems.
Two Way Slab Direct Design Pdf Beam Structure Stiffness Home work: for the transverse interior frame (frame c) of the flat plate floor with edge beams shown in figure below, by using the direct design method find: longitudinal distribution of total static moment at factored loads. This document discusses the direct design method for two way concrete slabs. it begins by stating the method is for vertical loads only and lists limitations on slab geometry and loading. When beams are used along the column lines in a two way floor system, an important parameter affecting the design is the relative size of the beam to the thickness of the slab. Comparison of a slab system by these two methods given by aci 318 05 code. a flat slab system is selected for the comparison of the design by the two specified methods.
Slab Design Pdf Structural Engineering Building Engineering When beams are used along the column lines in a two way floor system, an important parameter affecting the design is the relative size of the beam to the thickness of the slab. Comparison of a slab system by these two methods given by aci 318 05 code. a flat slab system is selected for the comparison of the design by the two specified methods. Numerical techniques such as finite difference and finite elements are required, but such methods require sophisticated software to be practical in design. the methods described in this chapter can be done by hand or with simple spreadsheets, and are sufficiently accurate for most design problems. Stucturepoint’s spslab software program solution utilizes the equivalent frame method to automate the process providing considerable time savings in the analysis and design of two way slab systems as compared to hand solutions using ddm or efm. This document compares two methods for designing flat slab systems: the direct design method (ddm) and equivalent frame method (efm). ddm uses coefficients to longitudinally distribute moments and has limitations, while efm calculates stiffness of elements and distributes moments based on stiffness without limitations. Different beam column frames are analyzed by three methods, direct design method (ddm), equivalent frame method (efm) and finite element method (fem) using computer software (staad pro).
