👉 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...

Chessboard-shaped quadrangular pyramid grid

Structural features: The spatial stiffness is smaller than that of the square pyramid grid, and the internal force of the lower chord increases. When the perimeter is arranged into a full cone, the stiffness is better. This grid has a short upper chord under compression and a long lower chord under tension, which can give full play to the role of the cross section of the rod and bear reasonable force.

 

Applicable conditions: Applicable to peripheral support grids with a rectangular plane shape, a side length ratio greater than 1.5, and small and medium spans.

What Are The Architectural Features Of The Space Frame Fabrication? Buildings processed by space frame   are a good form of construction, because the materials used are mainly metal, which have better toughness than other materials. This will not only help enhance the load-bearing capacity of the building itself, but also shorten the construction period. To reduce the difficulty of construction, let's talk about the characteristics of space frame   production   buildings： space frame 1. The   components of space   frame has good mechanical properties, and its stiffness and overall stability are better than those of general planar structures. 2. The space frame   structure has certain regularity and is convenient for construction. There are a   large number of same form components and nodes in the space frame   structure, which brings convenience to factory production and structural installation, ensu res   the quality of the project, acceler...

Strength and stability analysis of grid steel structures

 The strength problem of space frame steel structure refers to whether the maximum stress (or internal force) caused by the load of the structure or a single component exceeds the ultimate strength of the building material in a stable equilibrium state, so it is a stress problem. The value of ultimate strength depends on the characteristics of the material. For brittle materials such as concrete, its maximum strength can be taken, and for steel, its yield point is often taken.            The stability problem is different from the strength problem. It is mainly to find the unstable equilibrium state between the external load and the internal resistance of the structure, that is, the state where deformation begins to increase rapidly, so as to try to avoid entering this state. Therefore, it is a deformation problem. For example, for axial compression columns, due to instability and lateral deflection, a large amount of bending moment is added to the c...

The development status of the space frame structure space frame   structure has been developed greatly in the last 30 years, and has been widely used inside and outside. space frame   structure plan arrangement is flexible, space shape is beautiful, convenient for building shape processing and decoration, decoration, can adapt to different span, different plane shape, different support conditions, different functional needs of the building.   Especially in the roof structure of large and medium span, the space frame   structure shows its superiority and is used in large number of large sports buildings, public buildings, industrial buildings, and also widely used in the roof of some small buildings, such as gas stations, toll stations, large canopies. In recent years, with the wide application of electronic computers and the development of computing technology, the design efficiency of the space   frame structure has been greatly improved. The construction and i...
