Explain the development law of space frame structure in detail

-

 The development of the space frame structure is closely linked to the needs of life and production, the level of science and technology, and the development of material conditions. It has undergone a long development process.It has become one of the most important and active development areas in the architectural structure discipline of the 21st century. Reviewing the development process of the  structure, we can summarize some development laws of it.

The span of the space frame structure is getting bigger and bigger.From St. Peter’s Basilica in Ancient Rome to the "Millennium Dome" in London, England,its diameter has been expanded from 42m to 320m.Behind every innovation and development of the space frame structure, it is accompanied by the continuous increase of the span of the building.In recent years, more and more buildings have been built or under construction that exceed the span of the hectometer, and various forms of space frame structures have developed to super-span structures.For example, the span of the polyhedral space frame of my country's National Aquatics Center "Water Cube" reached 177m, and the span of the slightly curved space frame of the National "Bird's Nest" Stadium reached 330m.

The space frame structure develops towards light weight. With the increase of the span of this structure, the influence of the self-weight of the structure on the span becomes more and more obvious.Through the development process of space frame structure such as thin shell structure, space frame structure, reticulated shell structure, suspension cable structure and membrane structure, the weight of the structure is getting lighter and lighter.The reduction from 6400kg/m2 of the masonry dome to 10kg/m2 of the membrane structure reflects the rapid progress of the building structure.

From a single structure to a combined hybrid structure. The materials and structural forms used in the early structural forms were relatively simple. With the development of the space frame structure, a variety of materials are combined with each other, and a variety of components are hybridized with each other, complement each other, and develop into a variety of combined structures and hybrid structures.

In what areas are steel structures usually used

-

Steel structure manufacturers can process a wide variety of products, including the following categories: 1. Single and multi-story industrial and residential buildings. 2. Office buildings, primary and secondary schools, hospitals. 3. Luxury villas, tourism buildings. 4. Modern commercial buildings for various markets. 5. Mobile buildings (demountable buildings, emergency projects). The main building materials in membrane structure engineering are steel and membrane materials. For steel structures, the main processing flow includes: material feeding → cutting → inspection → assembly welding → rust removal → numbering packaging → factory. The precautions are: 1. Materials must have a material certificate. 2. According to the cutting length and rod specifications calculated by the designer, the rods are classified and stacked for easy construction in the next step. 3. According to the penetration size of the steel pipe, considering the influence of wall thickness and groove, the automa...

Three Methods of Space Frame Installation

  What are the 3 methods of space frame  installation ? SAFS steel structure professional technical staff share with customers and friends:   1.  Splicing the entire space frame  directly, after the completion  of  the corresponding ceiling method to hoist the entire space frame  into the air, and then within a certain hovering time, weld the space frame  in the corresponding position and connect it with the whole  building . This method is faster  to install, but has higher requirements for operators. 2.  The method is relatively mild, the space  frame works directly at a high place, and the space  frame is installed bit by bit through the part that intersects with the building, that is, starting from the surrounding area and completing the work at the final center point. The schedule  is very slow, but the operation difficulty is also reduced a lot. 3. This method is mainly applicable to the quadrangular pyrami...

Space frame has become one of the important fields of modern architectural structure

Since the 20th century, the spatial structure has been greatly developed all over the world. The space frame structure is a kind of space grid structure. The so-called "space structure" is relative to the "plane structure", which has the characteristics of three-dimensional function. The space structure can also be regarded as the expansion and deepening of the plane structure. Since the advent of the space structure, it has been welcomed by people for its high-efficiency mechanical performance, novel and beautiful form, and fast and convenient construction. In stadiums, convention centers, cultural facilities, transportation hubs and even industrial plants that require large spans and large spaces, space structures can be seen everywhere.   After a century of continuous development of space structure, in terms of structural form, in addition to space frame and reticulated shell, membrane structure, tensegrity system, open and close roof, and foldable structure are...
