Study on the interfacial shear behavior of steel reinforced concrete （src） members with stud connectors after fire

Statically push-out tests of 20 steel reinforced concrete short columns （srcSC） with stud connectors on the surface of shape steel after fire and two srcSC under ambient temperature were carried out, in order to study the failure mode, load-slip relationship and the interfacial shear transfer of src members after fire. Experimental results show that the typical failure modes and load-slip curves of srcSC after fire are almost the same as the case under ambient temperature. The interfacial shear transfer of srcSC declines exponentially not only with the increase of the peak temperature the specimen experienced but also with the increase of the peak temperature duration. The interfacial shear transfer of the specimens with studs arranged at the steel web is much higher than those with studs arranged at the steel flange. Empirical formulas of srcSC interfacial shear transfer after fire are proposed, and the calculated results generally agree well with the experimental results.

Research on Bond-Slip Constitutive Relation for steel reinforced concrete Members

Journal of Beijing Institute of Technology 2009年第2期18卷 152-156页

The constitutive relation of bond-slip on steel and concrete interface is proposed for short steel reinforced concrete （src） column. Based on the experimental research on bond-slip performance, a mechanical model of short src column in pulling or pushing test is established. By means of the elasto-plasticity theory the explicit formulation of bond-slip constitutive relation τ-s in different anchor-hold place of push and pull member is investigated under the conditions of balance and boundary. The study shows that the constitutive relation is relevant to the embedment length and the thickness of concrete cover. The results are continuous descriptions of bond-slip constitutive relation and can be used to analyze the non-linear performance of src members. Results indicate that the principle of the method is correct and it performs well for short src column.
