International Journal of Structural Engineering (IJStructE)

Forthcoming articles have been peer-reviewed and accepted for publication but are pending final changes, are not yet published and may not appear here in their final order of publication until they are assigned to issues. Therefore, the content conforms to our standards but the presentation (e.g. typesetting and proof-reading) is not necessarily up to the Inderscience standard. Additionally, titles, authors, abstracts and keywords may change before publication. Articles will not be published until the final proofs are validated by their authors.

Forthcoming articles must be purchased for the purposes of research, teaching and private study only. These articles can be cited using the expression "in press". For example: Smith, J. (in press). Article Title. Journal Title.

  • Free vibration and buckling analysis of laminated composite plates with cutouts of complicated shapes   Order a copy of this article
    by Leena Sinha, Rudra Narayan Nayak, Amar Nath Nayak 
    Abstract: This analysis commences with the formulation of a finite element model for laminated composite plates, taking into account the influences of aspect ratio, fiber orientation, and material anisotropy on the free vibration and buckling responses. This research additionally explores the impact of different shapes (circle, square, diamond and complicated) and sizes of cut-outs on the free vibration and buckling characteristics. The current analysis employs the four-nodded doubly curved shell S4R element from ABAQUS library featuring reduced integration and hourglass control. The present investigation focuses several studies, i.e., study on the mesh convergence, comparison with existing literature and effect of various parameters. It is observed from the study that various parameters considered here including shape and size of complicated cut-outs have substantial impact on the natural frequencies and buckling load of composite plates. The outcomes of this study will be very much helpful in the personalisation of laminated composite plate designs.
    Keywords: complicated cut-out; critical buckling load; finite element modelling; laminated composite plates; natural frequency.

  • Mechanical properties of YSt-355 fire-resistant steel tubular sections micro-alloyed with molybdenum (0.1%)   Order a copy of this article
    by Mohd Dilawar Bhat, Umesh Kumar Sharma, P.C. Ashwin Kumar 
    Abstract: A new category of low cost fire-resistant (FR) structural YSt-355FR steel cold-formed tubular sections micro alloyed with 0.1% molybdenum has been developed by Tata Steel, India. To investigate the degradation of mechanical properties at elevated temperatures, a series of steady-state tensile tests were performed within the temperature range of 24 C to 800 C. This research work presents the detailed results and discussion on strength, stiffness, and deformations of steel at ambient temperature (AT) and elevated temperature (ET). The stress-strain curve for mechanical properties and the reduction factors of yield strength, elastic modulus and ultimate strength were plotted and compared with current design standards and to those reported in the literature. The results led to conclusion that the codal design factors are either too conservative or unsafe. Consequently, new equations were proposed for the reduction factors at an elevated temperature suggesting its potential use in steel constructions subjected to fire conditions.
    Keywords: fire-resistant steel; FRS; elevated temperature; ET; reduction factor; steel tubular sections.
