| Abstract | A new online hybrid test system combined with substructuring techniques and incorporating finite element methods is developed. In the proposed system, numerical substructure analysis is conducted by ABAQUS/Explicit. An ABAQUS user subroutine is used as the interface between the main control program and ABAQUS to impose the target displacements and determine the reaction forces. No iteration is needed in this system, making it suitable for physical testing. As the approach also avoids the need to modify source code, it will be appealing to a number of real engineering applications. The proposed system adopts a separated-model framework, operator-splitting integration scheme, and data exchange through a socket mechanism. The earthquake responses of a simple steel moment-resisting frame are simulated, and the results obtained from the new system are compared to those obtained from the conventional analysis. It is found that the results obtained from the new system are accurate, demonstrating the applicability and efficiency of the proposed approach. The optimal test parameters are also studied to gain the most accurate results in the minimum time. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
