Cp and Cg Factors in the Log File for I-15 Method C&C Design (Bug 2635)

Combined vs Separate Cp and Cg

The Component and Cladding (C&C) loads for the NBC Commentary I - 15 method in the log file showed a combined pressure coefficient and gust factor CpCg, when in fact they are separate factors, similar to the main shear force resisting system (MWFRS) factors for this method. They are now shown as separate Cp and Cg factors.

The combined internal factor CgCpi is also now shown separately as Cgi and Cpi.

Inclusion of Internal Factors in External Factors

The factor showing was the difference between external and internal forces (NBC 4.1.7.1 3) ), which was contradicted by the legend to the table. It now shows the external coefficients only (4.1.7.1 1) ).

Inclusion of Ce for Internal Factors

The combined internal factor mistakenly included the value of exposure factor Ce for internal pressures, but this has been resolved by splitting the combined factor up.
