Equivalent Frame Method Pdf Beam Structure Column There are four main steps involved in the use of the equivalent frame method. step 1: the 3−d slab system is represented by four or more 2−d frames, just like in ddm. these design strips (or design frames) are separately considered for analysis and design. This document discusses the equivalent frame method for analyzing two way slabs. it introduces the concept of transforming a 3d structural frame into a 2d frame by considering the equivalent stiffness properties of slab beam members (ksb) and columns (kec).
Beam Column Design Pdf Beam Structure Young S Modulus In the equivalent frame method of analysis, the columns are considered to be attached to the continuous slab beam by torsional members that are transvers to the direction of the span for which moment are being found fig (4 2). This document discusses the equivalent frame method for analyzing two way slabs. it introduces the equivalent frame method, which transforms a 3d structural system into a 2d system by representing the stiffness of slab and beam members as ksb, and the modified stiffness of columns as kec. To calculate the factored moments using the moment distribution procedure we need to determine moment distribution factors and fixed end moments for the equivalent frame members (columns and slab beam members). Figure shows equivalent frame in a 5 story building. each frame is composed of columns and a broad continuous beam, named slab beam. this slab beam includes the portion of the slab bounded by panel centerlines on either side of the columns.

Figure shows equivalent frame in a 5 story building. each frame is composed of columns and a broad continuous beam, named slab beam. this slab beam includes the portion of the slab bounded by panel centerlines on either side of the columns. Equivalent frame method free download as powerpoint presentation (.ppt .pptx), pdf file (.pdf), text file (.txt) or view presentation slides online. the equivalent frame method involves dividing a 3d building into equivalent 2d frames for analysis. This paper describes basic procedure of equivalent frame method for two way slab analysis. Learn the equivalent frame method for structural analysis. this chapter covers calculations, stiffness, and moment distribution. Finally, numerical examples are provided to illustrate the effect of the proposed modified column stiffness on the analysis results using equivalent frame method.
