I. Preparatory Work Before Budgeting For a beginner, before making a steel structure budget, some knowledge is essential. First, you need to understand the construction process of steel structures, specifically how materials are received, cut, and constructed for each process. This will help prevent errors in later quantity calculations and highlight areas with higher material losses; you also need to learn steel structure construction standards, such as the arrangement, requirements, and quantity of column base plates; non-destructive testing; H-beam butt welds require non-destructive testing; knowing which is the H-beam flange and which is the H-beam web; the first-level weld of the flange requires 100% ultrasonic testing, and the second-level weld of the web requires 2

Current methods for reinforcing steel structures can be summarized as follows: 1) Increasing member section (such as steel bonding); 2) Improving structural force system (such as adding beams and columns); 3) Prestressed technology reinforcement method. Common methods for increasing the section size include increasing the section height, thickening the flange plate, and changing the section shape to a box section. The main reinforcement methods for increasing the steel structure section are steel bonding or carbon fiber cloth pasting. These two methods cause relatively little damage to the structure itself, and have developed relatively rapidly in China in recent years, with increasing applications. However, their applications in steel structure building reinforcement are relatively limited, especially...

Matters needing attention in the calculation process: 1.Regarding the format of engineering quantity calculation: 1.1The weight unit of steel structure is kg, the area unit is m2, and the length unit is m. The calculation results are all retained to one decimal place. 1.2When calculating the weight of components, the parts of the components can be numbered from bottom to top and from left to right, and calculated in this order. 1.3Format of the calculation formula: 1.3.1Plate: Specification × Length × Width × Quantity For example,-6×500×300×5 indicates that the plate thickness δ=6mm, the plate length is 500mm, and the width is 300mm

1. Strength: The ability of a component's cross-section material or connection to resist destruction. Strength calculation is to prevent the destruction of structural components or connections due to exceeding material strength. 2. Load-carrying capacity: The maximum internal force that a structure or component can withstand without being destroyed due to strength, stability, or fatigue; or the maximum internal force when a plastic analysis forms a failure mechanism; or the internal force when reaching a deformation that is unsuitable for continued load-bearing. 3. Brittle fracture: Generally refers to the sudden brittle fracture of steel structures under tensile stress without showing warning plastic deformation. 4. Standard value of strength: Yield point (yield strength) of steel specified in national standards

Ten Advantages of Structural Plant Buildings: 1. Earthquake Resistance: The roofs of low-rise villas are mostly sloped roofs. Therefore, the roof structure mainly adopts a triangular truss system made of cold-bent steel components. After the structural panels and gypsum boards are sealed, a very strong "plate-rib structural system" is formed. This structural system has stronger earthquake resistance and resistance to horizontal loads and is suitable for areas with seismic intensity of 8 degrees or more. 2. Wind Resistance: Steel structure buildings are light in weight, high in strength, good in overall rigidity, and strong in deformation ability. The self-weight of the building is only one-fifth of that of a brick-concrete structure, and it can withstand every

While China had remarkable achievements in iron structures in its early history, it remained stagnant in iron building technology for over two millennia due to the constraints of the feudal system and the lack of scientific development. It wasn't until the late 19th century that China began adopting modern steel structures. Following the establishment of the People's Republic of China, the application of steel structures significantly advanced, surpassing the past in both quantity and quality. High levels of expertise have been achieved in design, manufacturing, and installation, mastering the design and construction techniques for various complex buildings. Numerous large-scale and structurally complex steel structures, such as factory buildings and large-span steel structures, have been constructed throughout the country.

In recent years, steel structure buildings, as a type of green, circular, and low-carbon building that coexists harmoniously with nature, have been rapidly rising with the acceleration of China's urbanization process. Industry insiders believe this will create a huge market space for steel used in steel structures, while also placing new and higher demands on the steel used in steel structures. At present, problems such as the limited variety and poor quality stability of steel used in steel structures in China urgently need to be solved, and domestic steel companies also need to strengthen their attention to steel used in steel structures. Developing new steel varieties to meet the market demand for steel used in steel structures is a long and arduous task for steel enterprises. "Beautiful China" calls for green buildings. In terms of carbon emissions...

Shenyang starts rectifying fire safety issues in color steel structures. Li Guoxiao, the chief of the Shenyang Municipal Public Security Fire Brigade, stated that there are currently 255 color steel structure worker dormitories on construction sites across the city, of which 170 are substandard. Multiple fires have occurred in such color steel structure worker dormitories this year alone. Therefore, Shenyang requires construction units to complete the rectification tasks on time, according to standards and requirements, ensuring quality and quantity. Those who fail to rectify within the deadline will be sealed up according to law to ensure fire safety on construction sites.
