The Role of ASCE 7-05 in Modern Seismic Design The American Society of Civil Engineers (ASCE) Standard 7-05, formally titled Minimum Design Loads for Buildings and Other Structures
ASCE 7-10, which superseded ASCE 7-05, introduced several changes to the seismic design provisions, including: asce 7-05 seismic pdf
| Feature | ASCE 7-05 | ASCE 7-10/16 | |--------|-----------|---------------| | Ground motion basis | 2% probability of exceedance in 50 years (MCE) | Risk-targeted MCE with 1% in 50 years collapse probability | | Spectral response maps | Discrete contour maps | Interactive USGS web tools, but older maps still needed for legacy | | Site coefficients (Fa, Fv) | Based on ASCE 7-05 Table 11.4-1 and 11.4-2 | Updated coefficients, especially for Site Class E | | Vertical seismic force | 0.2 S_DS * D (dead load) | 0.2 S_DS * D, but exceptions added | | Near-fault factors | Not explicitly factored except via S_S/S_1 maps | Direct near-fault factors (N_A, N_V) introduced later | The Role of ASCE 7-05 in Modern Seismic
): ASCE 7-10 introduced risk-targeted maps, whereas 7-05 used traditional geometric mean maps. which superseded ASCE 7-05
