Abstract


Rise public buildings is a complex of modern socio-economic , technological and cultural development , internal water supply system is an important part of the building , has a significant impact on the reliability of the system to ensure the normal use of high-rise buildings within the high-rise building water supply system reliability of the research is very necessary . This paper analyzes the current situation of the domestic and foreign high-rise public buildings internal water supply system , the status quo of the reliability of the water supply system , on the basis of reliability theory , given the reliability of the concept of reliability index and its determination method and calculation methods ; introduction of a water supply system reliability model different components and water supply on the domestic water supply system , fire hydrant system , automatic sprinkler system reliability analysis and prediction ; Domestic water in the high-rise building is a continuous process and , therefore , to ensure the normal operation of the domestic water supply system is very necessary . The paper introduces the domestic water supply system , water supply ; various factors relative weights , using the Analytic Hierarchy Process (AHP) on the the feedwater way to select , by way of example, the establishment of a hierarchical model , the judgment matrix constructed three scales , seeking indirect AHP judgment matrix comparison various criteria under which water supply mode is superior, comprehensive evaluation to draw relatively better water supply ; pressure relief valve on the system , cisterns , tanks, pumps settings on the system reliability impact analysis and discussion . This paper introduces a high-rise building fire hydrant system , compare the reliability of the system under different water hydrant system , determine the need for high-rise building fire pool division and tank volume of several fire pump suction pipe arrangement reliability Comparison of decompression , anti - overpressure measures affect the reliability of the system are discussed . Automatic sprinkler system , This paper discusses the uncertainty of the water supply system , the calculated optimal reliability of the system , established to the timing requirements of the system when the total cost of the water supply system ( or reliability ) the reliability of the maximum ( or the total cost for the most provincial ) , and how each subsystem to allocate the optimum cost or the decision-making model for optimal reliability ; analysis of the main components of the system settings affect reliability , and the corresponding countermeasures.
