All valve units and valve mountings shal
32、l be provided by one manufacturer.1.2.1 Contractor Design of Structural Supports*NOTE: Delete reference to structural steel when valve casings are cast directly into concrete.*In lieu of the concrete openings and supports indicated, the Contractor may design openings and supports to accommodate the
33、proposed valve system. Design openings and framing using loads computed from the blast overpressures specified or indicated. Determine structural steel mechanical properties, such as minimum yield stress, tensile strength and member section properties, based on the proposed framing system. Dynamic i
34、ncrease factors shall be based on applicable strain rates and the concrete unconfined compressive strength, concrete reinforcement yield stress, and structural steel yield stress. Perform flexural analyses using equivalent single degree of freedom or other approved dynamic analysis methods. Deformat
35、ion limits shall be selected by the Contractor so that ultimate deflections do not inhibit proper valve unit operation.1.2.2 Sustained Blast Overpressures*NOTE: Delete this paragraph when only triangular overpressure waveforms are specified.Blast overpressure waveforms may be specified or indicated
36、as sustained (infinite duration) overpressures, triangular waveforms with peak overpressures and finite durations, or other pressure versus time histories. When the blast overpressures are low, a sustained overpressure can be specified or indicated conveniently without loss of economy. When the blas
37、t overpressures are high, specifying or indicating triangular waveforms will enhance economy and availability. The sustained overpressures shown in the text cover tested commercial products that are readily available. Some triangular waveform peak overpressures and durations for tested commercial pr
