Q:What is the ultimate capacity of steel structures?
I. The ultimate bearing capacity of steel structure means failure due to fatigue.Two 、 the ultimate limit of bearing capacity is the state that has been destroyed and can not be used. The serviceability limit state is also barely usedThree, the structure or component to the maximum carrying capacity, or reach the limit state of deformation which is not suitable for continued load.
Q:What is the proportion of paint for large steel structures and what thinners do they have?
Fluorocarbon paint main paint for large steel structure paint: curing agent: diluent = (0.8-1.2): 0.1: (0.2-0.4) (weight ratio). Large steel structure paint regardless of variety or form, is composed of film-forming material, secondary film-forming material and auxiliary material into three basic substances: membrane membrane material: also known as binder, film-forming material for most compounds such as organic polymer resin (natural rosin, lacquer paint), tung oil, linseed oil, soybean oil (fish oil, etc.), such as synthetic resin mix after high temperature reaction, also paint inorganic composition (such as inorganic zinc rich paint).
Q:What is the steel structure of portal frame and frame difference
Shelving structure: as the name suggests, a row of rows. Mainly used for single plant, by the roof and pillars and constitute the basis of horizontal plane, is the main bearing system of the plant, and then the plane frame is connected by the roof panel, crane beam, longitudinal support member, the overall space structure.
Q:What are the types of steel structures
The structure includes television tower, microwave tower, communication tower, high-voltage transmission line tower, petrochemical tower, atmospheric monitoring tower, launch tower, tower, tower, drilling travel lookout tower, tower, exhaust chimney, and most are made of steel structure of high-rise structure. 336m Heilongjiang TV Tower is the highest Chinese steel structure of the multifunctional TV Tower, the same type of 200 ~ 300m tower, there are many. The large tower mast structure China built in twentieth Century 60, -70's 200m 210m Guangzhou TV Tower, Shanghai TV Tower, 194m tower, transmission line across the Yangtze River in Nanjing 325m Beijing environmental climate mast. Completed in 1990, 212m Shantou TV Tower, 260m, Daqing TV Tower, are also steel structure. Large quantity and wide high-rise structure is communication tower and tower, along with the information and power development, the 50m around the tower throughout china.
Q:The role of stiffeners in steel structures?
Because the product can overcome the wall thickness from the difference of stress caused by the uneven deformation of the products.
Q:Can the steel structure workshop be welded?
Steel structure workshop can not be welded. Construction should be subject to design, light steel structure of industrial buildings, the design is friction type high-strength bolt connection; use period is strictly prohibited in the structure of welding.
Q:Steel structure, tied with brace pipe casing and how the difference? What difference?
The tie bar is a fixed connecting rod between the steel beams. The drawing is generally expressed as "XG" or "GXG", and the steel pipe is usually 114 in diameter,Brace is fixed between the purlin connecting rod, a straight and inclined brace brace, drawing on the general expression of ZLT, XLT, diameter of 12 bar for general use,The main casing support, support, drawing on the general expression of CG, up to 12 bar up to + 32x2.0 circular tube
Q:How can the steel structure be divided into Liang Hezhu?
The two are not the same, lies in the seismic design, allowing the beam stiffness is greatly reduced, in some cases it can even be allowed to quit the job, but the beam stiffness only allowed to reduce, and not allow it to withdraw from work, so the specification of secondary beam is not resting on the coupling beam however, secondary beams could take on the frame of the. General beam cross height is small (less than 5), with shear transfer, so the specification provides some of the beams and frame beam different in structure, is a requirement of coupling beams is encrypted and frame beam stirrup length can be divided into encryption area and non encrypted area, two is the reinforcement on the beam waist the made clear that "wall horizontal distribution reinforcement should be the waist beams through continuous beam configuration in the range when the beam section height pull; more than 700mm, the two sides of the longitudinal structure of reinforced beam is arranged along the high range (waist band) diameter should not be less than 10mm, the distance should not be greater than 200mm; cross ratio not more than 2.5 of the beam, the longitudinal structure of reinforced beams (on both sides of the waist band) area of the reinforcement ratio should not be less than 0.3%" and will be incorporated into the provisions of a strong, and waist reinforcement in beams as long as the "when the beam web height h W = 450mm, in the two side beams along the height of the longitudinal structure configuration should be reinforced, each side of the vertical reinforcement (not including the upper and lower beam reinforcement and erect steel) 0.1% of the cross-sectional area should not be less than the web section area of bhw, and the distance should be less than 200mm." And not a strong clause.
Q:What is the foundation and the main structure of the construction project?
It is a complete construction system constructed with foundation and foundation. It is the foundation of safe use of construction project, and is the carrier and important component of construction engineering safety, stability and reliability.
Q:What is the brittle fracture of steel or steel structure?
Tensile strength or yield strength of steel in tensile tests
