| Abstract | Six full-scale steel-concrete composite substructures with full and partial shear connection representing half bay within a moment-resisting frame were built and tested both in a, quasi-static cyclic and pseudo-dynamic regime. The specimens embodied two composite beams with full shear connection and four companion beams with two different degrees of partial shear connection all with exterior rigid joints.Tests were conducted in a set-up purposely designed to impose to specimens reversed horizontal displacements in a low-cycle high amplitude regime. The characteristics of the test apparatus ready for different structural members subjected to horizontal loading are illustrated. Moreover, the seismic performances of the specimens in terms of yielding and of maximum strength capacity as well as of displacement ductility are assessed. Finally, the accuracy of a European code calibrated upon monotonic loading is provided and other local characteristics of the composite substructure behaviour with low partial shear connection are commented upon.Six poutres mixtes béton-acier à échelle réelle ayant des connections au cisaillement complètes et partielles, représentant une démi-travée, dans le cadre d’une structure qui résiste aux moments, ont été construites et testées aussi bien dans un régime cyclique quasi-statique que dans un régime pseudo-dynamique. Les spécimens sont constitués de deux poutres composites ayant des connections au cisaillement, complètes et quatre poutres, de même dimension ayant deux différents degrés de connections au cisaillement partielles, toutes ayant des jointures extérieures et rigides.Les essais ont été faits selon une configuration étudiée intentionnellement pour imposer aux spécimens des déplacements horizontaux et opposés dans un régime à bas cycle et à haute amplitude. On expose les caractéristiques de l’appareillage destiné aux essais des différents membres structuraux soumis aux charges horizontales. En outre, les performances sismiques des spécimens ont été évaluées aussi bien du point de vue de l’éervement, et de la capacité maximale de résistance que de la ductilité du déplacement. Enfin, une comparaison d’un code européen calibré sur une charge monotone est vérifiée et d’autres caractéristiques locales de la conduite de la substructure mixte ayant un degré bas des connections au cisaillement, sont commentées. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
