• Abstract:
  NJDOT has adopted “AASHTO Guide Specifications for LRFD Seismic Bridge Design” approved by the Highway ; Subcommittee on Bridges and Structures in 2007. The main objective of research presented in this report has ; been to resolve following issues for an effective implementation of AASHTO Guide Specifications: (i) AASHTO ; Guide Specifications don’t provide any specific guidelines for classification and performance requirements for ; critical bridges. This issue is resolved by proposing performance requirements and classification criteria for ; critical bridges in New Jersey. (ii) Guide Specifications present displacement based approach, which is ; significantly different than the force-based approach in previous versions of seismic guidelines. Nine examples ; of reinforce concrete and steel bridges of different characteristics (spans, skew, etc.) illustrating the use of newly ; adopted seismic guide specifications have been developed for training of engineers in New Jersey. (iii) NJDOT ; maintains an extensive electronic database of soil boring logs for the State of New Jersey. A zip-code based soil ; site map for New Jersey has been developed by analyzing soil boring data and other available New Jersey soil ; information. This map can be used for a rapid seismic hazard evaluation for the entire state or for a network of ; bridges in the state. (iv) AASHTO Guide Specifications introduce seismic design categories based on local ; seismicity and soil properties. Using the seismic soil map and zip code based seismic spectra provided in the ; AAHSTO Guide Specifications, seismic design category maps for critical and standard bridges in New Jersey ; have been developed. A detailed analysis has also been carried out to develop liquefaction potential maps for ; the state of New Jersey. These maps can be used to determine the need for a detailed liquefaction analysis for ; a particular bridge site. A detailed guideline on developing site-specific spectra has also been developed, since ; AASHTO Guide Specifications recommend site-specific spectra for critical bridges. (v) Existing bridges in New ; Jersey are required to be retrofitted on the basis of 2006 Edition of the “Seismic Retrofitting Manual for Highway ; Structures: Part 1 – Bridges”. Simplified guidelines for seismic retrofit of existing bridges, that are consistent ; with guidelines for the design of new bridges in AASHTO Guide Specifications, have been developed.
