What are the design difficulties of trusses?

Difficulties in the design of truss structures usually include the following:

Load analysis and design: Truss structure is usually used to bear large loads, such as wind load, snow load, earthquake load, etc.. Therefore, designers need to conduct detailed load analysis to ensure that the truss structure can operate safely and stably under various working conditions.

Material Selection and Optimization: Selection of appropriate materials is crucial to the performance of truss structure. Designers need to consider the strength, stiffness, durability and cost of the materials and optimize the design of the materials to meet the performance requirements of the structure.

Connection Node Design: Connection node in truss structure is the key part of the structure, which directly affects the stability and bearing capacity of the structure. The design of suitable connection nodes needs to take into account the force situation, material properties and feasibility of manufacturing and construction.

Structural stability and vibration control: truss structures are prone to stability problems when subjected to external loads, such as local buckling and overall instability. Designers need to take corresponding measures, such as strengthening the stiffness of the structure and setting up bracing, to ensure the stability and safety of the structure. In addition, vibration control is also an important consideration, especially in large-span truss structures, where excessive vibration of the structure due to external excitation needs to be prevented.

Construction and Manufacturing Difficulties: Truss structures usually have complex geometries and structural layouts, so they may face some challenges during construction and manufacturing, such as high machining accuracy requirements and high welding technology requirements. Designers need to consider these factors and work closely with the constructor and fabricator to ensure the quality of the structure and smooth construction.
