Steel structure workshop column and top beam how to use materials?
Beam using 20# column using 18# steel I-beam, a total of 8, two to 16 lateral roots, the use of 16#C type steel purlin.
The column load is larger, and relatively high age, should choose the lattice column in materials under the same lattice column can increase the section moment of inertia and radius of gyration, improve the stiffness and stability of pillars.
When the load is relatively small, steel section is preferred, such as H steel. When the load is large, the welded I-beam can be selected;
