What is the difference between grid construction and truss construction?

 A grid construction is a spatial structure composed of several prefabricated components connected by joints in a specific grid pattern. It is typically a lattice structure composed of spring steel beams connected at the ends. Currently, it is widely used and economically cost-effective. For example, it has been used in conference and exhibition centers, stadiums, and other large commercial buildings.

Compared to grid construction, grid construction can meet the requirements of various architectural styles through the use of vertical prefabricated components at the bottom chord of the spherical grid and curved joints. It is particularly advantageous for construction of arches and random curved shapes. The structural mechanical properties of a spatial truss structure show that when its length-to-width ratio exceeds 1.5, its structural properties change from double to single-sided. Therefore, for most rectangular buildings, it is primarily single-sided.

Truss structures are similar to flat steel trusses and are single-sided structures. However, by increasing the width of the spring rods, the stability of the spring rods is improved, ensuring uniform stability in all directions and reducing material consumption. Truss structures have gradually developed within the spherical grid. Compared to grid structures, truss structures offer distinct advantages and versatility, and the amount of stainless steel used in their construction is also more economical.

In recent years, the grid manufacturing industry has experienced rapid growth, but what is the difference between spherical grids and trusses? Grid manufacturers have gained relevant knowledge. With the continuous improvement of steel production in my country, steel frame structures have become increasingly important in construction, and seamless steel pipe structures have also made significant progress. The greatest advantage of seamless steel pipe structures is their ability to perfectly combine people's functional and practical requirements with the economic benefits of construction.

  Hangzhou Century Center, which is the tallest building under construction in Hangzhou and the tallest twin tower building in the Hangzhou Bay area, is known as the gate of Hangzhou. The wings of the two towers of Hangzhou Gate, together with the surrounding Olympic Sports Center, natatorium, International Expo Center, as well as the civic center, international Convention center, and grand Theater on the other side of the Qian River, form a "seven-star bright" urban picture. The Gate of Hangzhou is like a cloud floating in the seven stars, with a strong sense of design and visual impact.   The main body of Hangzhou Gate is composed of symmetrical 63-story east and west towers, with a building height of 302.6m and a total construction area of about 532,500 square meters. The east and west towers are connected by steel arch Bridges on the 1st to 6th floors above ground. The maximum span of the bridge is 85m at the north and south ends, the minimum span is 55m in the middle...

The Development of the Structural Form of Gas Station Canopy

Since Portland cement was invented in 1824, after half a century of research and development, it was not until the middle of the 19th century that concrete structures began to be applied. Because the quality of concrete and cement was relatively poor at that time, and the theory of design technology had not yet started, the development was relatively slow. At the end of the 19th century and the beginning of the 20th century, China began to build buildings with reinforced concrete structures, such as Shamian in Guangzhou and The Bund in Shanghai. However, when our country was first established, the steel output was very low, only 1.35 million tons per year. At that time, the construction of steel structures in China could only rely on the economic and technical assistance of the Soviet Union. It can be seen that the appearance of reinforced concrete structures in China was earlier than steel structures. The structure of the gas station canopy in China was a reinforced concrete frame s...

Prefab aircraft hangar construction

  With the rapid progress of science and technology, the development of aviation and aerospace, the design of aircraft is constantly innovating. The continuous emergence of large aircraft will inevitably lead to the emergence of large-span maintenance depots. According to the current requirements for the clear span of the maintenance warehouse, the span of the maintenance warehouse is basically more than 60m, which is already a large-span structure. In addition, the increase of flight frequency also puts forward higher requirements for the structure and function of airport-supporting facilities such as hangars. The  prefab hangar  has high requirements on the structure of the roof due to its large span, large opening and large lifting capacity of hanging cranes. Because of its outstanding advantages, the grid structure can meet the needs of hangar construction, and has been used in more and more hangar arrays at home and abroad. Due to the special requirements of the...
