Design and Optimization of the Annular Water Supply System of Fire Hydrant in Buildings

With the development of economy and the speed of urbanization, people have paid more attention to fire protection. While it's not enough to only rely on the external fire protection, and the internal fire protection of the building should be strengthened. There are many basic fire water supply system formulas at home and abroad. While there is no hydraulic specific calculation method of various types of fire pipe network, furthermore, the main fire control mean in our country is to put out a fire through the fire hydrant, which is mainly the annular water supply system. On the basis of the relevant theory, the traditional calculation methods were simply summarized, then, based on the nodal accumulative method and finite element method, a new finite element method was redesigned and compared with the traditional calculation method, and it was obtained that this method could optimize the design of the annular water supply system of fire hydrant in buildings.
