# 1605.4 Structural Integrity Load Combinations—Alternate Load Path Method

JUMP TO FULL CODE CHAPTER
Where specifically required by Sections 1615 through 1617, elements and components shall be designed to resist the forces calculated using the following combination of factored loads:

where:

The live load component

Equation 16-27

where:

f_{1} |
= | 0.25 for buildings in Risk Category II. |

f_{1} |
= | 0.5 for buildings in Risk Category III or IV. |

f_{2} |
= | 0 for buildings in Risk Category II. |

f_{2} |
= | 0.33 for buildings in Risk Category III or IV. |

The live load component

*f*need not be greater than the reduced live load.
