Introduction

In architecturestructural engineering or building, a purlin (or historically purline, purloyne, purling, perling) is any longitudinal, horizontal, structural member in roof except a type of framing with what is called a crown plate. In traditional timber framing there are three basic types of purlin: purlin plate, principal purlin and common purlin.

Q:How to calculate the allowable slenderness ratio of steel structures under compression?
The slenderness ratio of the structure is I = l/i, and the radius is gyration radius.The buckling stress in the axial compression members of steel structures is only related to slenderness ratio.
Q:Steel plate for steel structure, what kind of steel plate is it
Carbon steel, low alloy high strength structural steel and high quality carbon structural steel are often used in building engineering.
Q:Ask the two grouting steel structure column anchor bolts for what?
But mainly by the anchor bolts to stress. The steel column base connection is hinged and rigid, rigid two pouring pouring depth 100mm, pouring depth two time pouring hinged 50mm in steel structure regulation on the stress problem. Of course I saw just according to make a person views.
Q:Why are the main and main beam joints of steel structures articulated?
If there is only one side of the beam, the beam bending moment into girder bending moment, for the opening section, the torsional ability is not strong, the box section can be made rigid, but the torque for an I-shaped cross section is best not to. For the main beam with both secondary beams on both sides, the bending moment at the joint of both sides of the secondary beam is small, and the bending moment on both sides can be counteracted each other, and it is feasible to make a rigid connection. But in fact, the existence of live load may cause a great difference in the bending moment between the two sides, so it is possible to produce a larger torque when the rigid joint is used.
Q:What does a product frame refer to in a steel structure workshop?
Steel structure workshop refers to the steel column and steel beam on each axis. The steel structure workshop is made up of N pieces, a steel frame including steel columns, steel beams and high-strength bolts for connection.
Q:In the steel structure safety margin refers to what?
When the calculations of structural steel to the strength and size of your theory, you have to leave, to increase the size or structure of steel used high performance steel, this is the safety margin, or accident probability, general safety margin will add a lot of, or even several times.
Q:Tall steel columns with studs what effect is there?
In China, most of the high-rise building load-bearing structure use of steel column, steel encased concrete in the outer layer, the stud used in steel columns of concrete layer surface is used to connect the column surface, to increase the connection area, increase the contact surface shear strength, the steel column and the concrete surface, firmly combined stress common.
Q:What is the difference between steel structure, light steel workshop, color steel room and movable room?
The frame of light steel structure buildings are H steel, I-beam, door type steel frame and Rachel purline, retaining structure is also useful for color plate and masonry wall. Multi-purpose in large companies, factories, warehouses, exhibition halls, integrated stadiums, shopping malls and so on.
Q:Steel structure workshop and equipment have static electricity is how?
Remind: if you hit the steel structure was not necessarily static, static steel structure, but you have the electrostatic savings, met steel structure rapidly after being led into the earth, you have been playing the static feeling, this is the most general.
Q:What effect does the welding slag not have on the steel structure or the reinforced concrete structure?
Check the pressure leakage test of the pipeline. Water test, if there is a leak point, because the welding slag cover, the exudation of water may not be out of the leak point, is not conducive to check the location of leakage point.
