Steel Structure Warehouse:

1.The steel structure of the connection method: welding connection
2.Steel structure design common norms are as follows: "Steel Design Code" (GB50017-2003) Cold-formed steel structure technical specifications" (GB50018-2002) "Construction Quality Acceptance of Steel" (GB50205-2001) "Technical Specification for welded steel structure" (JGJ81-2002, J218-2002) "Technical Specification for Steel Structures of Tall Buildings" (JGJ99-98)
3.The characteristics of steel Light weight steel structure Higher reliability of steel work Steel anti-vibration (earthquake), impact and good Steel structure for a higher degree of industrialization Steel can be assembled quickly and accurately Large steel interior space Likely to cause sealing structure Steel corrosive Poor fire-resistant steel Recyclable steel shorter duration
4.Commonly used steel grades and performance of steel Carbon

Q:What does LL represent in steel structures?
Common steel girders may be floor beams or other common beamsIn terms of frame beams
Q:What is the performance and function of steel structure engineering?
Earthquake resistance: most of the roofs of low rise villas are pitched roofs. Light steel members in sealed end structural plate and plaster board, formed a very strong "plate structure" of this structural system has stronger earthquake resistance and load capacity, suitable for seismic intensity of 8 degrees in the area.
Q:Steel plate for steel structure, what kind of steel plate is it
To make a steel plate, such a phrase, I think, is a little worse.This word is a relatively large range, according to that there is no special requirements, can use general steel: carbon steel structure can be, such as Q235, Q345, Q235 belong to ordinary carbon steel structure, Q345 is the last name 16Mn, belongs to low alloy series.But if it's special, it can be bridge, steel plate, Q235q, etc.. Q345q and so on.
Q:How to calculate the allowable slenderness ratio of steel structures under compression?
It can be seen from the formula that the concept of slenderness ratio takes into account the end constraint of the component, the length of the component itself and the section characteristics of the component.The effect of slenderness ratio on the stability calculation of compressive members is obvious, because the larger the slenderness ratio is, the more easily it is unstable. Here are some formulas for calculating axial and flexural members. There are parameters related to slenderness ratio.
Q:Where are welded parts of steel structures to be subjected to nondestructive testing?
The appearance of the weld is smooth and beautiful, and there shall be no welding defects, such as blowhole, undercut, flowing, welding failure, incomplete sealing angle and non sealing.
Q:What is the two steel structure?
Two definition: in the steel structure frame, shear wall, frame some non bearing masonry, shear in engineering structural column, some need to be completed in the lintel decoration before the steel structure, known as the two steel structure.
Q:What is the life span of steel structure?
The life of steel is infinite (without corrosion). There are many factors affecting the life of steel structures, in which the reference period of live load is 50 years. So the design cycle is 50 years. The most important special projects in the country can be listed for 100 years.
Q:Brief discussion on safety measures of steel structure installation
Steel structure safety protection: steel structure construction (installation) in general, each column in the factory according to a certain height to make, tower in accordance with each storey height of 12 ~ 13m production, to the site construction speed is faster. The installation of the operating personnel working time are most of the primary and secondary operation in the narrow beam or walk, in my project of steel structure of each layer height of 12 ~ 13m as an example, according to the standard of 2m aerial work as the starting point, it has exceeded the aerial work safety requirements, so in the end, the 3.5m column installation when conditions permit next, should put up the double level safety net for protection, and add a layer of horizontal safety net in each installation section of main structure column, the level of network security protection and steeplejacks protection distance is generally not more than 10m.
Q:What is the material in the steel structure?
Steel structure is mainly made of steel material, and it is one of the main types of building structure.
Q:Which is better, the steel structure or the frame structure?
Concrete beams and concrete walls are called shear wallsCommonly used in ordinary high-rise residential, and Fangxing very complex multi-storey villas and villas.Advantages: load-bearing structure for sheet concrete wall, the room can not see the edges and corners of columns, more suitable for residential than the frame structure. The concrete wall has the strongest seismic resistance, and the building safety is very high.Disadvantages: large amount of concrete, from the major, the total height is usually no more than 150m. The concrete wall is a high strength load-bearing wall, and the room can not be dismantled.
