This paper describes the experimental tests carried out at the University of Minho using Perfobond connectors and lightweight concrete. The main objective of these tests is to describe the connection behaviour and to analyse and compare the contribution of the different elements to the slip measured between the steel profile and the concrete slab. In this way, it is possible to define the connection ductility. The test configuration follows some of the EC4 recommendations and repeats some dispositions referred to by Oguejiofor and Ferreira. The parameters under study are the concrete strength, the reinforcement disposition and the Perfobond rib existence and spacing of holes. An important comparison with the experimental results achieved by different authors using normal weight concrete may then be established. #

“…In its upper part, the mesh is equipped with circular openings through which the reinforcement is pulled. Through this arrangement, the mesh is analogous to steel connection meshes as known in steel-concrete structures [14,15]. In its bottom part, the mesh is fitted with design modifications that ensure an even distribution of glue over the plywood's surface.…”

This paper presents results of experimental and mathematical analysis of stiffness characteristics of a composite timber-concrete structure. The composite timberconcrete structure presented herein is non-typical compared to similar types of building structures. The interaction between the timber and concrete part of the composite cross-section is not based on metal connecting elements, but it is ensured by a glued-in perforated mesh made of plywood. The paper presents results of experimental and mathematical analysis for material alternatives of the solution of the glued joint. The slip modulus values were determined experimentally. Data obtained from the experiment evaluated by means of regression analysis. Test results were also used as input data for the compilation of a 3D model of a composite structure by means of the 3D finite element model. On the basis of result evaluation, it can be stated that the stress-deformation behaviour at shear loading of this specific timber-concrete composite structure can be affected by the type of glue used. Parameters of the 3D model of both alternative of the structure represent well the behaviour of the composite structure and the model can be used for predicting design parameters of a building structure.

ABSTRACT:In continuous steel-concrete composite structures, cracking of the concrete slab in the hogging bending moment region decreases the global stiffness of composite structures and reduces the effect of continuity, resulting in making the structural behaviors highly nonlinear even for low stress levels. Because of this, special consideration is necessary. The purpose of the present study is to investigate the effects of rubber-latex mortar and different types of shear connectors on inelastic behavior of composite girders subjected to hogging moment. Two overturned simply supported steel-concrete composite girders with different shear connectors such as Studs and Perfo-Bond Strips (PBLs) were tested under concentrated load in the mid-span. Based on the experimental observations, a three-dimensional FE model capable of analyzing the composite beams subjected to negative bending moment was built. Strength and load bearing capacity, sectional strain distribution and movement of composite neutral axis before and after cracking were observed in the test and compared with the numerical results, and the results predicted by this modeling method are in good agreement with those obtained from the tests. Research results indicate that the PBL connectors could slightly improve the rigidity of the composite girder under both the serviceability limit state and the ultimate limit state, while Stud specimens have relatively better mechanical behavior in regard to the initial crack and the "crack closure" of the test specimens. Besides, research results indicate that the current specifications such as AASHTO, JSCE, and EUROCODE-4 can provide appropriate values for ultimate strength of a composite girder under negative bending moment. Moreover, noise reduction, shear stud stiffness increase and the adhesion bonding effect of rubber-latex mortar on interface slip were confirmed in the tests.
