Finite element analysis on flexural loading capacity of composite slim beam with deep deck in the hogging moment region;

In order to simpligy theoretical analysis model of composite slim beam with deep deck and improve the shape of deck in China at present,and through ANSYS software,finite element analysis(FEA) was used in the positive and negative moment zone.

For the steel-concrete composite slim floors,the deck shape has a significant influence on the loading capacity of the composite slim floor with deep deck and the rationalization of deck shape will not only improve the loading capacity of composite slim floors,but also bring on a good economic performance.

Factors analysis on effective width of simply supported composite slim beam;

Nonlinear finite element analysis on flexural loading capacity of composite slim beam with deep deck;

Loading capacity of composite slim beam in the sagging moment region;

Reinforced concrete composite flat beams can not only well meet the requirements in architecture significantly reduce the structural floor height and enclosure expenditures as well as foundation loads but also cut down steel consumption and costs of the structure.

With reference to the structural design of one multi story lightweight steel house,the authors mainly discuss how to design the composite flat beams in large bay buildings.

The slim floor beams,which are partly contained within the floor slab,achieves a minimum depth of building,and the flat floor is beneficial because the building services can be run in any direction.

The slim floor beams,which are partly contained within the floor slab,have good performance under fire.
