- Vult and Vasd on Construction Documents 1 - Eng-Tips
If they still want ASD wind speeds, why bother adopting the ASCE 7-10 I have also put the nominal and ASD PRESSURES on the design document, and I agree that helps clarify when a jurisdiction recently adopts the new wind speeds, but I stand by the fact that the Vasd provides no realistic benefit Section 1603 1 directs you to go to 1609 3
- ACI 318-19 Aggregate Size Discrepancy - Eng-Tips
Section 26 4 2 1 a 5 requires the aggregates not to exceed the following 5) Nominal maximum size of coarse aggregate not to exceed the least of (i), (ii), and (iii): (i) one fifth the narrowest dimension between sides of forms (ii) one-third the depth of slabs
- Nominal Wall Thickness for Olets (B31. 1) Weld Size PWHT?
The nominal thickness for PWHT is well defined in the 2010 edition of ASME B31 1; see section 132 4 2 E If you are using an older edition of ASME B31 1, what is the edition? Also, the 2010 Edition of ASME B31 1 was an excellent improvement in defining nominal thickness with Figure 127 4 8 D and E

- ASME B. 31. 3 Pressure Test Limits - Eng-Tips
a nominal pressure stress or longitudinal stress in excess of the yield strength at test temperature or a pressure more than 1 5 times the component rating at test temperature, the test pressure may be reduced to the maximum pressure that will not exceed the lesser of the yield strength or 1 5 times the component ratings at test temperature
- 2:1 Head straight flange in SEC. VIII, DIV. 1 1 - Eng-Tips
If you input 19 for SF in PV Elite, that means to the program you are using 19 nominal plate to achieve 13 min head after forming Head for internal and external pressure will be based on 13 SF which is part of the shell will be based on 19 for internal and external pressure The total weight will be based on 19, not 13
- Decimal places - Drafting Standards, GD T Tolerance Analysis
I wasn't questioning the legality of having tolerances in the title block for directly dimensioned features Its the tolerance not matching the number of implied decimal places in the nominal that's a pet peeve I would write XXXX+ - 0010" to be in compliance with Y14 5
