Abstract

The state of the art of behaviour of Steel Castellated Beams is explain in this paper. The present research status of behavior of castellated beams is not mature and need much through study compared to beams without openings in the web. The existence of various shapes of openings such as circular, hexagonal, rectan-gular, octagonal and oval etc. in beams web add some additional failure modes namely; lateral-torsional buck-ling of web posts, web post buckling due to shear force, formation of four plastic hinges around the corners of openings, rupture of welded of joints in the castellated beams over a conventional steel beams. A review of experimental and analytical work carried out on castellated steel beams has been presented. The paper also focuses on the influence of various parameters such as types of openings, size of openings, spacing of the openings, aspect ratio, various numbers of openings and strengthening on the behavior of steel beams with web openings

城堡式钢梁的性能:最新技术评论

本文介绍了钢蜂窝梁的性能现状。与腹板无开孔梁相比，蜂窝梁的性能研究现状尚不成熟，需要大量的研究。梁腹板中存在圆形、六边形、矩形、八角形和椭圆形等各种形状的开孔，增加了一些额外的破坏模式，即；腹板支柱的侧向扭转屈曲，由于剪切力引起的腹板支柱屈曲，开口拐角处形成四个塑性铰链，槽型梁与传统钢梁的焊接接头断裂。对蜂窝钢梁的试验和分析工作进行了综述。文中还重点讨论了开孔类型、开孔尺寸、开孔间距、纵横比、开孔数量和加固等参数对腹板开孔钢梁性能的影响

期刊介绍： The Electronic Journal of Structural Engineering (EJSE) is an international forum for the dissemination and discussion of leading edge research and practical applications in Structural Engineering. It comprises peer-reviewed technical papers, discussions and comments, and also news about conferences, workshops etc. in Structural Engineering. Original papers are invited from individuals involved in the field of structural engineering and construction. The areas of special interests include the following, but are not limited to: Analytical and design methods Bridges and High-rise Buildings Case studies and failure investigation Innovations in design and new technology New Construction Materials Performance of Structures Prefabrication Technology Repairs, Strengthening, and Maintenance Stability and Scaffolding Engineering Soil-structure interaction Standards and Codes of Practice Structural and solid mechanics Structural Safety and Reliability Testing Technologies Vibration, impact and structural dynamics Wind and earthquake engineering. EJSE is seeking original papers (research or state-of the art reviews) of the highest quality for consideration for publication. The papers will be published within 3 to 6 months. The papers are expected to make a significant contribution to the research and development activities of the academic and professional engineering community.
