Lecture 4 Two Way Slab Ddm Direct Design Method Pdf Beam Direct design method oximate procedure for the analysis and design of two way slabs. it is limited to slab systems subjected to uniformly distr bution loads and supported on equally or nearly spaced columns. the method uses a set of co. This table covers general limitations, drawbacks, advantages, and cost time efficiency of each method where it helps the engineer in deciding which method to use based on the project complexity, schedule, and budget.
Two Way Slab Direct Design Pdf Beam Structure Stiffness 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. These lower limits for two way slab systems are summarized: there is a minimum of three continuous spans in each direction. panels must be rectangular with the ratio of longer to shorter span center to center of supports within a panel not greater than 2.0. What is direct design method? what are the limitation of direct design method? design of two way slab more. As per nscp 2015 section 408. direction design method ddm is an approximate method established by the code to determine the design moments in uniform loaded two way slabs. limitations (sec. 408.10.): there shall be at least three continuous spans in each direction. adjacent spans in each direction must not differ by more than one third of the.

Aci 318 permits the use of direct design method (ddm) and equivalent frame method (efm) for the gravity load analysis of orthogonal frames and is applicable to flat plates, flat slabs, and slabs with beams. The document discusses the direct design method for analyzing two way slab systems. it outlines limitations on the use of this method, including requirements for panel geometry and load distributions. Direct design method limitations of the ddm: spans in each direction. thus, a nine panel structure (3 by 3) is the sm rectangular panels must have a long span short span ratio that is ≤ 2. successive span lengths in each direction shall not differ by more than one third of the longer span. This research work is an effort to see the difference between two methods, first method is ddm having some limitations and based on coefficients and second is efm having no limitations.
