Analysis And Study Conversion Methods Of Confirmation Equivalent Uniform Distributed Load Of Non-uniform Distributed Load On Reinforced Concrete Slab

At present, reinforced concrete slab is the most commonly used component of one in architectural engineering. In engineering practice, with the function of modern architecture increasingly complex and changeable, as well as the construction of the indoor aesthetic requirements increase. The graphic layouts of construction structure are restricted more and more. Sometimes because of the restrictions of architectural graphic layout, the partition wall are requested to put aside on the floor slab directly, namely there is no beam under the partition walls, Or because the functional requirements of the building, which requests to lay small column on the floor slab. Which is far different from the traditional requirements of laying beams under the partition walls and of the columns are laid on the beams. This makes non-uniform distributed load on the floor slab. What about the performance of the floor slab under the non-uniform distributed load. How to calculate the bending moment and the deflection? And how to design the floor slab under the non-uniform distributed load? Whether which have the same performance as the floor slab under uniform distributed load? If structural designers are not clear the performance of the floor slab under the non-uniform distributed load. They can not make the reasonable design. How to equal the non-uniform distributed load for equivalent uniform distributed load. Especially how to determine the equivalent uniform distributed load of partition wall load on the floor slab. Although the current "Construction Structure Load Standard" also providing a number of provisions. But which are not very applicable for the designers. And which are not very convenient for the designers. In most time, the designers simply divide the non-uniform distributed load under the floor slab by the total area of the whole floor slab to get uniform distributed load. And regard the floor slab under non-uniform distributed load as the floor slab under uniform distributed load to design. This approach is reasonable or not?In response to those issues, this article will take the traditional theory of plates and shells as the rationale. And take the reinforced concrete slab under the non-uniform distributed load (linear load and concentrated load) as the research object. And analysis the performance of the reinforced concrete slab under the non-uniform distributed load (linear load and concentrated load). And we obtained some distribution rules about the bending moment and deflection of the reinforced concrete slab under the non-uniform distributed load. And has produced the bending moment and deflection approximate calculation formulas. It has carried on the discussion to the methods how to equal the non-uniform distributed load for equivalent uniform distributed load, and compared with some simple computational methods at present. Which may supply the design reference. And which has the important theory and the project significance.
