Q:Does the cross section of corrugated steel H have this section in PKPM?
At present, the Bowen of the corrugated web is a waveform determined by rigorous tests (which can be trapezoidal, sinusoidal, rectangular, discounted, etc.)
Q:House built with H steel, two story buildings, all columns below, no load wall, beam with steel beam, what type of H steel?
Square tubes are generally used in the post, opening and other locations,C type steel purlin is used in roofing, wall or roof panel, as wall panel support,Channel steel, angle steel and so on are generally used in support position, crane beam is also commonly used i-beam;
Q:248 H steel GB thickness?
GB H type steel: narrow flange HN250 * 125 models, 248 x 124 x 5 x 8 - 3289mm, cross-sectional area, weight 25.8kg/m.
Q:What's the difference between hot rolled H steel and welded H? Is it the same weight?
Stable performance and good internal organization. Due to continuous casting from smelting to rolling, steel production than hot-rolled H steel process requirements, equipment capacity, control level, detection means is high, so the welding of H steel internal organization, chemical composition, various properties (mechanical properties, process performance indicators are reliable and stable etc.).
Q:H steel or I-beam, which bearing good?
The length of the I-beam is small and the height is big. It can only bear the force in one direction. H steel is deep in groove and big in thickness and can bear two directions of force.
Q:In actual steel structure engineering, why use H steel in large number, but seldom use I-beam? What's the difference between the two?
In actual steel structure engineering, a large number of H steel is adopted, but less I-beam is used, because the section of H steel is larger than that of I-beam, and the bearing capacity is higher and the cost is lower
Q:Light thin-walled H steel, in addition to welding, is there any hot rolling?
Yes, the 2 largest domestic hot-rolled H steel producers are Laiwu Steel and Maanshan Iron and steel
Q:Specification for splicing length specification of H steel in steel structures
Flange splicing length should not be less than 600mm; web splicing width should not be less than 300mm, the length should not be less than 600mm. the flange and web is required to achieve at the same time
Q:Method for calculating weight of H steel
Sectional area=(H+2T =(TW)2bt 580×2×14)+2×280×12×14 = 144.64cm2
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.
