摘要: The composite steel-concrete beam-columns in which steel shapes are encased concrete and second-order effects significant were studied from 16 specimens loaded to failure. Loading included combinations of axial transverse forces producing a wide range different external eccentricities. Observations the physical tests indicate that, for static loads, bonding condition at interface rib connectors surrounding has small effect on ultimate strength. also show that ACI 318 assumption maximum usable strain 0.003 extreme compression fibers near load is valid such beam-columns. Analyses based 318, Eurocode 4, finite-element modeling procedures compared test results provided further insight into understanding structural behavior
