EFFECT OF UPGRADING WFP CONNECTION WITH DOUBLE-I-SECTION COLUMN USING SIDEPLATE-WITH-OPENING ON FRAME PERFORMANCE
The objective of this paper is to evaluation of frame performance with WFP connections and double-I-section column and compares it with the upgraded performance of frame when the connections are retrofitted with Sideplate-with-Opening. So 3, 7 and 12 story frame are designed with the both existing and upgraded connections. Typically 20 connections with different beam and column size are designed. 6 connections were selected for finite element study. Moment-rotation of connection, panelzone and rotational capacity of the selected connections are extracted using finite element method. Parametric studies are performed to develop equation for prediction of remaining 14 connections behavior. Frame performance level is calculated based on interstory drift to connection rotational capacity. Frame response is calculated with nonlinear time history analysis under 7 known earthquake. Connections and panelzones are modeled with multilinear and linear springs, respectively.
