👉 Project location: Nigerian coast 👉 Project type: Mine warehouse (span 100 metres, length 125 metres) 1. Structural Design  Span and Length:  The mine warehouse has a span of 100 metres and a length of 125 metres, employing a large-span steel structure design to ensure structural stability and load-bearing capacity.  It is recommended to use a steel truss structure or space frame structure to meet the large-span requirements and optimise material usage.  The structural design must consider wind loads, seismic loads, and dynamic loads during the operation of the bucket wheel excavator. Foundation Design:  Since the project is located by the sea, the foundation may be relatively soft. It is recommended to use deep foundation design (such as pile foundations) to ensure structural stability.  Foundation construction must consider the impact of groundwater levels and saline-alkali environments, and foundation reinforcement should be carried out when necessa...

What to pay attention to in the design of a steel truss?

  (1) Cross-section design of rods: The cross-section form of truss rods should be selected according to the conditions of saving steel, convenient connection and simple manufacture, and attention should be paid to make the length and slenderness ratio of rods in two main axes direction (the ratio between calculated length of rods and radius of rotation of the cross-section) as similar as possible, and should meet the requirements of strength, stability and length and slenderness ratio. (2) Strength and stability check: in the calculation of the strength and stability of the bar, the internal force is considered according to the axial force, when the bar is subject to axial force and bending moment at the same time, it should be considered according to the eccentricity of the force and its common role. When calculating the stability and slenderness ratio of the bars, the in-plane and out-of-plane directions of the truss or the unfavorable direction of the larger slenderness ratio ...
