T/CSPSTC 119-2023 Standard Operating Procedure for Static Load Test and Evaluation of Prefabricated U-shaped Beams in Urban Rail Transit
Basic Information
Scope
This document specifies the quality inspection of prefabricated U-shaped beams for urban rail transit (including the prohibition of tensile stress in longitudinal bending, and the allowance of tensile stress but prohibition of cracking in longitudinal bending) and the static load test method and evaluation of their ultimate bearing capacity, including test conditions, objectives and contents, general requirements, testing devices and instruments, test preparation and installation of test beams, test loading, test evaluation, static load test records and test reports, and requirements for safety and protective measures. This document is applicable to the quality inspection and ultimate bearing capacity evaluation of prefabricated prestressed concrete U-shaped beams in factories. Other similar types of U-shaped beams can be referenced and used for reference.
