1613.6.7 Minimum Distance for Building Separation
All buildings and structures shall be separated from adjoining structures. Separations shall allow for the maximum inelastic response displacement (δM). δM shall be determined at critical locations with consideration for both translational and torsional displacements of the structure using Equation 16-44.
|Cd||=||Deflection amplification factor in Table 12.2-1 of ASCE 7.|
|δmax||=||Maximum displacement defined in Section 22.214.171.124 of ASCE 7.|
|I||=||Importance factor in accordance with Section 11.5.1 of ASCE 7.|
Adjacent buildings on the same property shall be separated by a distance not less than δMT, determined by Equation 16-45.
|δM1, δM2||=||The maximum inelastic response displacements of the adjacent buildings in accordance with Equation 16-44.|
Where a structure adjoins a property line not common to a public way, the structure shall also be set back from the property line by not less than the maximum inelastic response displacement, δM, of that structure.
- Smaller separations or property line setbacks shall be permitted when justified by rational analyses.
- Buildings and structures assigned to Seismic Design Category A, B or C.
