Steel structure is one of the main types of building structures.The structure is mainly composed of steel beam, steel column, steel truss and other components made of section steel and steel plate, etc.Because of its light weight and simple construction, it is widely used in large factories, stadiums, super high-rise and other fields.

First, focus on the design of steel structure engineering. The purpose of steel structure engineering design is to build structures that can meet a variety of predetermined functional requirements: economical, reasonable, safe and applicable, and ensure quality.The so-called structural functional requirements are as follows:

(1) security

The structure can withstand the various functions that may occur during normal construction and normal use, as well as maintain the required overall stability during and after accidental events specified in the design.

(2) the applicability

In the case of normal load, the influence of normal use of large deformation.

(3) the durability

The structure has good working performance to meet the normal use requirements, under normal maintenance, the structure has enough durability, such as no serious corrosion to affect the service life of the structure.

Steel structure only meets the above functional requirements can not be called a good steel structure manufacturers, steel structure engineering also need to keep the state of the structure under the limit state.Like other building structures, the ultimate state of steel structure is divided into the ultimate state of bearing capacity and the ultimate state of normal use.

1. Ultimate state of carrying capacity

Refers to the limiting state of a structure or member when it reaches its maximum carrying capacity or when deformation occurs that is not suitable for continued carrying.These include capsizing, strength failure, loss of stability, fatigue failure, structural transition to a maneuvering system or excessive plastic deformation.

2. Limit state of normal use

Refers to the limit state of a structure or component when it reaches a specified limit for normal use or durability.When this limit value is reached, although the structure or member still has the capacity to continue bearing, the deformation under normal load has made the structure or member unfit for continued use, including excessive deformation and local damage under static load or severe vibration under dynamic load.

As long as the above functional requirements and limit state requirements are met, such steel structure engineering design and production is qualified, such steel structure factory construction and installation is in line with the requirements.

Dalian guangtong steel structure co., ltd. is a steel structure construction industry as the target, set design, production, installation in one of the dalian steel structure company, with a high level of new building materials development, research as the backing;The implementation of the company's management system and strict product quality management, we always believe that good reputation comes from excellent quality, starting from strong strength.
