Strip And Disc Continuous Shooting Loads Constraint Deformation

Strip and Disc Continuous Shooting Loads Constraint deformation

Load, pronunciation: hè zài. ("Contained" with "carrying" means, then read four) refers to the structure or components to produce internal forces and deformation of external forces and other factors. Or habitually refers to the application of engineering structures in the engineering structure or component effects of the various direct effects, common are: structural weight, floor live load, roof live load, roof ash load, vehicle load, crane load, equipment Dynamic load and wind, snow, ice, waves and other natural loads.

Causing the structure to lose balance or damage the external effects are: directly applied to the structure of the various forces, customary known as the load, such as structural weight (dead load), live load, fouling load, snow load, wind load; Classes are indirect effects that refer to other effects that cause structural deformation and constrained deformation, such as concrete shrinkage, temperature change, welding deformation, foundation subsidence, and so on. 

Attention to the purpose of the load is to meet the needs of building structural design to meet the safety requirements, economic and reasonable requirements.

The design of the load is suitable for the structural design of various projects

The access standard: GB50068 load statistical parameters, the design base period of 50 years.

Classification

The load has a different classification method

Time classification

1 permanent load (dead load), its value does not change with time; or changes that are negligible compared to the mean. Such as structural self-weight, earth pressure, prestressed foundation settlement, concrete shrinkage, welding deformation and so on. The dead load, also known as the permanent load, is applied to the structural structure of the same (or its changes compared with the average can be ignored) load. Such as structural self-weight, plus a permanent load-bearing, non-load-bearing structural components and building decoration components of the weight, earth pressure and so on. Because the dead load is always applied continuously over the entire lifetime, it is necessary to consider its long-term effects when designing the structure. Structural self-weight, generally based on the structure of the geometric size and material density of the standard value (also known as the nominal value) to determine.

The house is made up of some of the heavier structural members of the foundation, the wall (column), the beam, and the plate. They must first bear their own weight, this is the dead load. In addition, the ground, roof, ceiling, wall plaster and doors and windows are loaded.

2 variable load (live load), during the design of the reference period, its value changes with time, and the change in value and the average compared to the load can not be ignored. Such as floor live load, roof live load and fouling load, crane load, wind load, snow load and so on.
