Complex Structural Steel Engineering, Spiral Staircases, cat-ladders and Double-Curved Structures

CHEC GOLD Engineering has experienced the entire transformation process of building steel structures, from inception to complexity, from small to large, and from complexity to large-scale construction.
We have participated in and supervised government and private projects, residential and commercial buildings, pressure vessels, underground pipelines, floodgates, foundation supports, engineering machinery manufacturing, and structural steel welding projects, accumulating extensive industry experience.
We provide dedicated services for your projects with reliable professional knowledge and skills.

Characteristics of Complex Steel Structure Engineering

  • Complex Component System
    Building steel structures constitute a vast force-bearing system comprising numerous components. These components come together to form a unified whole, bearing self-weight loads and various environmental loads. Static calculations compounded with time factors make the calculation and analysis of building steel structures more complex.
    For instance, components of the same section bear significantly different loads on the sunny side and the shaded side. These complex load variations are transmitted through welds and directly impact the safety of the structure, making welds a critical focus.
  • Diversity of Processes
    From design to fabrication and installation, building steel structures involve multiple intricate processes. During the formation of steel structures, components are progressively assembled into systems. Force transformations are achieved through splicing and unloading, eventually forming a complete self-supporting structure.
    This entire process is highly dynamic, with the structure’s stiffness changing continuously throughout the formation process. It cannot be simplistically assumed that the final internal force distribution is the same as the result of applying all loads simultaneously. This necessitates considering construction effects during the design process.
  • Coordination Among Different Structures
    Building steel structures come in various types, including frame structures, grid structures, shell structures, suspension structures, and space truss structures, among others. The boundaries between these structure types are not always clear-cut. The coordination among these structures affects overall stiffness and internal force distribution.
  • Complexity of Material Selection
    Building steel structures employ a wide range of steel materials, from low-alloy steel to high-strength steel, and new materials continue to emerge. The use of high-strength steel can reduce plate thickness and save material, but it significantly increases welding difficulty.
    Different steel materials have varying welding process parameters, such as preheating temperature and energy input, which need to be considered based on material characteristics. This requires designing welding processes tailored to material properties rather than using a one-size-fits-all approach.
  • Node Design
    Nodes are critical components of building steel structures, and their complexity directly affects the structure’s safety. Node forms in building steel structures vary, including beam-column nodes, column-base nodes, diagonal brace nodes, etc., and they experience complex force conditions.
    Some nodes need to bear complex loads from multiple directions. This requires controlling anisotropic stress and strain in different nodes to ensure node quality.
  • Selection of Welding Technology and Processes
    Building steel structure welding involves a wide range of welding technologies and processes, including manual arc welding, gas shielded welding, submerged arc welding, and electroslag welding, among others, each with its own characteristics.
    Manual arc welding is convenient for complex shapes; gas shielded welding is fast, facilitating automation; submerged arc welding is suitable for thick plate welding. Engineering construction requires selecting the appropriate welding process based on the complexity of the area.

Curved Steel Structures

More and more architects are designing structures that incorporate curved steel profiles, whether they are angle steel, bars, beams, channels, tees, pipes, or tubes. The increased use of curved steel results from the continuous enhancement of manufacturers’ bending capabilities and the desire of owners, architects, and engineers to build exceptionally beautiful and efficient structures.
CHEC GOLD Engineering’s design team utilizes BIM three-dimensional design technology, replacing traditional two-dimensional design methods, to create extraordinary forms for curved steel structures. The design team engages in parametric collaborative design, establishing a unified collaborative design model framework and unfolding the entire project, creating a “design skeleton.” The major components are further broken down based on the framework, progressively designing each part.
Components before unfolding can be conditionally associated through assembly, allowing parts to be independently designed after unfolding, achieving collaborative design objectives. Alternatively, component design can be done separately, with assembly taking place later. This enhances engineering efficiency.
Parametric design is another fundamental feature of three-dimensional design software, distinguishing it from traditional two-dimensional design methods. One of the outstanding advantages of parametric design is that it allows easy self-adjustment during design modifications.
