Q:What's the difference between I-beam and H steel?
H steel is a kind of economical section steel with better mechanical properties than I-beam. Its shape is named after its English letter "H". The flange of hot rolled H steel is wider than that of I-beam, big lateral rigidity and strong bending resistance. Under the same specifications, H steel is lighter than i-beam.
Q:The difference and use of H type steel steel and steel.
H steel is a new type of economical construction steel. H type steel cross section shape is reasonable in economy, good mechanical properties, rolling each point on the extended section is uniform, small internal stress, compared with the ordinary beam, a section modulus, light weight, saving advantages of metal, can make the building structure to reduce 30-40%; and because of its inner and outer legs parallel leg end is right, assembled into components, welding, riveting work can save up to 25%. Often used in large capacity requirements, large cross section stability, such as buildings, high-rise buildings, as well as bridges, ships, lifting transport machinery, equipment foundation, support, foundation piles.
Q:What does H steel.R represent?
It should mean the rounded radius of H steel.
Q:What is the theoretical weight of welded H - section steel 900*350*20*30?
H steel is mainly used in engineering, plant, equipment, machinery and equipment, bridges, highways, houses, etc., with good mechanical and physical properties, firm and energy-saving and environmental protection. H steel is an economical section steel, widely used in industry, construction, bridge, oil drilling and so on
Q:Which is better, I-beam or HN steel?
Mainly to see what you mean, I-beam and HN steel beams of what size, or look at section size. Generally I-beam is stronger
Q:What's the difference between I-beam and H?
The difference and application description of H steel and I-beamI-steel whether ordinary or light, because the section size are relatively high and narrow, so the moment of inertia of the main sections of the two sleeve is large, therefore, generally only can be directly used in the web plane bending member or the composition of lattice stress components. It is not suitable for the axial compression member or the bent member perpendicular to the web plane, which has great limitations in its application.
Q:What does H steel column H300*250*6*10-90 represent in steel structure?
Steel column: a column made of steel. Large and medium-sized industrial buildings (see map [CFST column construction plant "), long-span public buildings, high-rise buildings, homes, light work platform, the Zhanqiao and the support column, most of the steel column. The classified steel column can be divided into solid column and lattice column (Figure 1[steel column) in the form of cross section. Section form solid column with steel column section [the whole), is the most commonly used I-section; lattice column section is divided into two limbs or more limbs, the limbs with batten or batten plate contact (Figure 2b[] section steel column), when the load is larger than m, when the width of steel consumption is saved.
Q:What are the specifications for H steel HW, HB, HN?
HW is a H type steel flange height and width substantially equal; mainly used for reinforced concrete frame column steel column, also known as rigid steel column; column is mainly used in steel structure.
Q:How is the weight of H steel calculated?
RA=RB=P/2 Mc=Mmax=Pl/4 fc=fmax=Pl^3/48EI A= B=Pl^2/16EI symbol and theta theta P - Q - N; concentrated load, uniform load, N; R - bearing force, the direction of the action is positive, N; M - bending moment, the compression of the upper section, lower tension is positive, Nm; Q, the shear. The adjacent section of the torque in a clockwise direction is positive, N; F, deflection, downward displacement is positive, mm; angle theta, clockwise rotation as positive degrees; E - Gpa; I - elastic modulus, cross-sectional moment of inertia, m^4; L = x/. =x'/l, zeta, alpha beta gamma = a/l, =b/l, =c/l from two aspects: first, from the beam considering shear stress second, the bending stress is considered. The maximum available shear strength of steel can be found from the steel sheet, T, Tmax=Q/Ib[BH^2/8-< (B-b), h^2>/8]: Tmax is the maximum shear strength. The maximum shear load of the beam can be calculated by replacing the available shear strength T. Q is the uniformly distributed load, and the section moment of inertia of I is B, which can be found in the steel table. (cm^4) the maximum width of the section of i-beam. B is the minimum width of I-beam section, h is the height of minimum width section of i-beam. H is the calculation of the height normal stress of the maximum width section of I-beam: Ysigma=M/W, M=, maximum bending moment = load, travel distance, W= flexural modulus. With the maximum allowable stress of Ysigma=, the maximum value of the load can be obtained.
Q:How to control the welding deformation made of H steel
Features are as follows: wide flange and large lateral rigidity. Good bending resistance. The two surfaces of the flange are parallel to each other, so that the connection, processing and installation are simple. Compared with the welding drawing I-beam, the utility model has the advantages of low cost, high precision, little residual stress, no expensive welding materials and welding seam detection, and the cost of steel structure production is saved by about 30%. Under the same section load, the H steel structure of hot rolled 15%-20% steel is less than that of traditional steel structure. Compared with the concrete structure, the hot rolled H steel structure can increase the use area of 6%, while the structural weight is reduced by 20% and 30%, and the internal force of the structural design is reduced. The H steel can be processed into T steel, and the castellated beams can form various section forms to meet the demands of engineering design and manufacture. H steel is mainly used in engineering, plant, equipment, machinery and equipment, bridges, highways, houses, etc., with good mechanical and physical properties, firm and energy-saving and environmental protection. H steel is a kind of economical type section steel, widely used in industry, buildings, bridges, oil drilling platforms, according to the forecast in 2005 China's H steel demand of about 2 million 500 thousand tons, 5 million tons of demand in 2010, but the H steel of China's annual production capacity of 1 million 200 thousand tons, the market demand is very great.
