Channel 12, span 5 meters, how much weight can be carried?
Check the ordinary channel capacity should be B (i.e. limited channel material can only bear much of the force, this is the state), because the common channel is Q235 type steel structure, the allowable stress of [b]=1400kg/c square meters
Some of the basic parameters of the 20b channel check (per unit length, weight g, section modulus W), check the "mechanical design manual" g=25.77kg/m=0.2577kg/cm W=191.4cm fand.
8.5 meters tall, *11.8, inside the half second layer, 3 wall, 11.8 meters side horizontal pull a beam (bearing), I would like to ask how much channel (GB)
List the maximum bearing moment formula: M=1/8GL - -1/8gL -, (L=500cm, G: the calculation of the maximum uniform load, G: ibid.)
