Special Issue Information

Dear Colleagues,

We are pleased to invite you to contribute to this Special Issue entitled “Development of Connections in Steel Structures for Construction”. Technological developments in the fields of advanced manufacturing, steel construction, and robotics have led to the design of new and proprietary steel connections which can simplify the steel assembly process, increase efficiency, and promote the automation of construction processes. While numerical analysis and modeling support their development, physical testing is a critical step in validating the structural performance of new connection types and assembly systems, enabling standardization and certification under national and international codes of practice.

This Special Issue aims to collate state-of-the-art developments in this area; papers are invited that address the development of connections in structural steel, including but not limited to:

  • Design and development of new steel connections, including design for deconstruction and reuse;
  • Physical testing of new connections at elemental scale or at full scale within a structural steel assembly, including the implementation of novel sensing approaches;
  • Static and dynamic testing of steel connections, including fatigue testing;
  • Advanced manufacturing techniques optimizing steel connection performance;
  • Automated assembly of steel structures, including use of robotics;
  • Construction efficiency in steel structures.

We look forward to receiving your submissions.

Designing prequalified connections is a process of iterative calculation, in which certain dimensions are varied until the verifications and restrictions stipulated by the standard are met. This is a slow process that can be automated using various software and optimized using a new design method called generative design, which consists of establishing restrictions so that the script delivers multiple solutions that meet the objectives. This research was conducted based on the design science research (DSR) methodology and focused on developing a method to design moment-resisting steel connections, specifically end-plate connections, using generative design in a building information modeling (BIM) environment. From this, it was possible to obtain several end-plate connection design alternatives, and technical validation was carried out to verify the functionality of the program using a verification method proposed by a civil engineer.

Structural joint configurations realized with serrated steel surfaces have started to be used in the construction fields to assemble the primary and the secondary structural members of civil engineering structures. The main advantages of these joint configurations rely on their flexibility to accommodate construction tolerances and their slip-resistant load-bearing mechanism against dynamic loading conditions. Therefore, it is important to reliably establish the characteristic value of the friction coefficient or in other words the slip factor between the serrated steel surfaces to design reliable slip-resistant connections. In this study, the characteristic slip factor between the CNC-cut serrated surfaces prepared from S355J2 grade steel plates is determined to investigate the impact of the CNC-cutting procedure on the slip-resistant load-bearing behaviour of steel-to-steel interfaces. Five experimental tests were performed according to EN1090-2, Annex G. The results are presented as the load-slip curves, variation of the bolt pre-tension load level, nominal and actual slip factors for the tested configuration of the CNC-cut serrated steel-to-steel interface.

Pinned base plate connections are the most common base connection used in low-rise steel buildings. In this research, an extensive parametric study is performed using the Finite Element (FE) software Abaqus to determine the elastic rotational stiffness, moment resistance, and energy absorption of the pinned base plate connection connected to a reinforced concrete footing and subjected to an eccentric axial load. The developed FE model is validated using experimental results from the literature. Moreover, an intensive parametric study is conducted to understand the behavior of these connections better. The investigated parameters include the base plate thickness, anchor bolt diameter, and arrangement and number of bolts. The most effective parameters that affect the elastic rotational stiffness and moment resistance of pinned base connections are the anchor bolt arrangement and diameter. The maximum increase in the rotational stiffness was 53% for the anchor bolt diameter of 30 mm when the base plate thickness increased from 12 mm to 30 mm. Based on the base plate thickness, the moment resistance is improved by 150–260% when the bolt diameter increases from 12 mm to 30 mm. Full article
