Abstract

ABSTRACT This paper investigates a novel joint method for connecting rectangular hollow section (RHS) members in reticulated shells. It is proposed to overcome the problem of connecting rectangular tubes using the traditional joint (cast steel joint) under dead and snow load. A case study is a structure in the eastern region of Turkey that was built on August 20, 2019. This museum-style structure is 40 meters long and 20 meters wide, with an oval shape. In the middle of the building, five tree-shaped columns were used. ANSYS is used to create a refined 3D solid model of the RHS joint. The moment-rotation results show that the proposed RHS joint (plate steel joint) for connecting rectangular hollow section members can be considered a semi-rigid connection and preferred due to its lower cost and weight. Moreover, the dissipated energy capacity has been raised by approximately 3.22 times when the plate steel type model has been used instead of the cast steel type. The stress ratios indicate that the connection stress in the Cast steel type model is lower than the stress in the Plate steel type model. As a result, the Cast steel type model is determined to be incredibly safe and more rigid than plate steel. Furthermore, since the resulting stress rates are lower than those of S355 steel, both models (cast and plate steel type models) can be used for connecting RHS.

网壳矩形空心截面连接螺栓连接分析

摘要本文研究了一种连接网壳矩形空心构件的新方法。提出了在恒载和雪荷载作用下采用传统节点（铸钢节点）连接矩形管的方法。案例研究是土耳其东部地区于2019年8月20日建造的一座建筑。这座博物馆式建筑长40米，宽20米，呈椭圆形。在建筑的中间，使用了五根树形的柱子。ANSYS用于创建RHS接头的精细三维实体模型。力矩旋转结果表明，用于连接矩形空心截面构件的RHS节点（钢板节点）可以被认为是半刚性连接，并且由于其较低的成本和重量而被首选。此外，当使用钢板型模型代替铸钢型时，耗散能量容量提高了约3.22倍。应力比表明，铸钢型模型的连接应力低于钢板型模型的应力。因此，铸钢型模型被确定为比钢板更安全、更坚固。此外，由于所得应力率低于S355钢的应力率，两种模型（铸钢型和钢板型模型）均可用于连接RHS。

期刊介绍： Informative and accessible, this publication analyses and discusses the integration of the main stages within the process of design and construction and multidisciplinary collaborative working between the different professionals involved. Ideal for practitioners and academics alike, Architectural Engineering and Design Management examines specific topics on architectural technology, engineering design, building performance and building design management to highlight the interfaces between them and bridge the gap between architectural abstraction and engineering practice. Coverage includes: -Integration of architectural and engineering design -Integration of building design and construction -Building design management; planning and co-ordination, information and knowledge management, vale engineering and value management -Collaborative working and collaborative visualisation in building design -Architectural technology -Sustainable architecture -Building thermal, aural, visual and structural performance -Education and architectural engineering This journal is a valuable resource for professionals and academics (teachers, researchers and students) involved in building design and construction, including the following disciplines: -Architecture -Building Engineering -Building Service Engineering -Building Physics -Design Management and Design Coordination -Facilities Management Published papers will report on both fundamental research dealing with theoretical work and applied research dealing with practical issues and industrial innovations. In this way, readers explore the interaction between technical considerations and management issues.
