Although the combination of reinforced concrete plaster mold rib floor system has been widely used in engineering , but also the design theory and calculation methods stagnation in engineering practice , and most of the engineering staff understand their specific circumstances force is not and more . First , the article describes the proposed plate method , quasi - beam method , the look-up table method , cross- ribbed beam structure , method of four beam system , the internal forces and deformation calculation method , and proposed a the stiffness contribution coefficient β this concept , the gypsum composite formwork on the rigidity of the structure of the overall stiffness contribution through the rib beam , so that the existing method of calculation is more accurate calculation of the force and deformation of reinforced concrete plaster combination mode rib floor system . Secondly, the actual situation of the working conditions of the dozen large general-purpose software ANSYS finite element analysis, summarized stiffness contribution coefficient β is calculated and summed up the reinforced concrete plaster combination mode the rib floor system applicable across a high- ratio range , the actual project has a practical significance . Again , as members of reinforced concrete plaster combination mode rib floor system coordination flat beams were analyzed and summarized . Finally , by comparison with ordinary flat-slab architecture , reinforced concrete plaster combination mode rib floor system has the advantages of simple construction , the structure is beautiful , reasonable force , turning waste into treasure , in line with national industrial policies ; and ordinary economic Comparison of the beam and plate system , we more clearly see this new structural system has an unparalleled advantage in the actual project .
