Steel structure design standard

Steel structure design standard: GB500 17—20 17.

The national standard "Steel Structure Design Standard" was approved and issued by the Ministry of Housing and Urban-Rural Development in February 20 17717, numbered as GB 50017-2017, from 20 18.

The main technical contents of the standard include: general rules, terms and symbols, basic design provisions, materials, structural analysis and stability design, flexural members, axial stress members, tension-bending members, compression-bending members, stiffened steel plate shear walls, plastic and moment amplitude modulation design, connections, joints, steel-concrete composite beams, concrete-filled steel tubular columns and joints, fatigue calculation and brittle fracture prevention design, and seismic performance-based steel structures.

Standard is one of the important standards in the field of building engineering. This standard comprehensively summarizes the research results and engineering practice experience in the field of steel structure in China in recent years. This technology is scientific, reasonable and operable, and its promulgation and implementation will further promote the sustainable development of steel structure buildings.

Steel structure engineering construction requirements:

1, to do a good job of inspection and selection of steel structure production and installation units.

2. Strictly review the steel structure manufacturing process and installation construction organization design submitted by the contractor.

3. Pay full attention to the supervision work in the production stage.

4. Supervision in the installation stage.

5. Test work on steel structure engineering.

6. Several other important quality control points of steel structure engineering?

The key points of several other important quality control points in steel structure engineering are as follows:

1. Embedding of anchor bolts. The embedded quality of anchor bolts directly affects the installation quality of steel structure. Controlling the position, verticality, length and elevation of anchor bolts (groups) is of great significance for reducing reaming and adjusting workload (even avoiding rework) and improving the quality of structural installation. The embedding method of anchor bolts can be direct embedding method or reserved hole method.

Before foundation concrete pouring, the supervision engineer must strictly check the rationality and reliability of the construction method of embedded bolts, and whether the measured indicators are within the scope specified in the specification.

2, welding engineering quality control. Welding engineering is one of the most important sub-projects in steel structure manufacturing and installation engineering. The supervision engineer must be engaged in all aspects of preliminary preparation, welding process and finished product inspection, and do a good job in quality control of welding engineering.
