For example, a site with a controlling earthquake magnitude of 7.0 should have candidate time histories selected from earthquakes with M between 6.5 and 7.5.Д¤ Processing of Time Histories Recommendations (cont.) Monday, January 13, In addition to earthquake magnitude, it is important that the candidate time histories have the appropriate source-to-site distance. We found that the PEER web site was particularly useful because its records had been already pre-processed for engineering evaluations The earthquake magnitude, M, of candidate time histories should be within M of the controlling fault magnitude for the proposed site. The candidate time histories for spectral matching should be selected from the National Geophysical Data Center (NGDC), U.S.G.S., PEER and California Strong Ground Motion Instrumentation Program, or other appropriate strong motion databases. This information can be determined from the candidate site by a deagregation of the probabilistic seismic hazard analysis (PHSA) using the tools from the following website: 2. The controlling earthquake is that earthquake and its associated fault that has the largest contribution to the seismic hazard for a given site. The candidate time histories for the analyses should come from earthquakes that have earthquake magnitude and source-to-site distance that are approximately the same as the controlling earthquake magnitude and source distance associated with the proposed site. plot of both components of time history selected in problem 1 plot of both components of rotated time histories plot of spectrally matched time histories (fault normal and fault parallel components) plot of target spectrum versus matched spectrum for both components plot of match and non-matched time histories superimposed on each other plot of baseline-corrected, spectrally-matched time histories for the fault normal and fault parallel directionsДЈ Processing of Time Histories Recommendations Monday, JanuRecommendations for selecting of candidate time histories for spectral matching and ground response analyses 1. Please provide the following plots for the fault normal and fault parallel components of ground motion. This processing should include, rotation, filtering, spectral matching and baseline correction, as appropriate (20 points). Use Seismosignal and Seismomatch to process the time histories and match them to the target spectrum. This set should consist two components: fault normal component and a fault parallel component. Using the selected time history in problem 1, develop 1 set of spectrumcompatible horizontal acceleration time histories for analyses of the dam for potential rupture of this fault system. Use the link for Holocene to Latest Pleistocene found on this page.

Adjust the target spectrum as described in this lecture for the fault normal component only (10 points).Дў Processing of Time Histories Processing of Time Histories (cont.) Monday, January 13, Geological mapping has shown that the Hurricane fault is a significant seismic source: Using this link, you can download the Google earth kml file required to locate the Hurricane Fault in Google earth. Adjust the target spectrum developed in problem 2 for near fault effects (i.e., fault directivity). State all assumptions that you made in developing the target spectrum (20 points). Select from the PEER strong motion database, one candidate time history that is consistent with the controlling earthquake Use ASCE 7-05 to develop a design target spectrum for this site for site class C conditions.

The deaggregation information can be found at: Show how you use this information to determine the M and R values that are appropriate for the subsequent steps in this homework (10 points). Using the USGS mapping for 2008, determine the controlling earthquake in terms of magnitude (M) and distance from the seismic source to the project site (R) for this area. Using the information provided in this lecture do the following: 1.
