Description
This web seminar consists of two parts, one on highlights of seismic design codes for highway bridges and the other on new developments in accelerated bridge construction (ABC) and innovation in areas of moderate to high seismicity.
The first part discusses the seismic design of highway bridges according to the AASHTO LRFD Bridge Design Specifications, 7th Edition including 2016 Interim Revisions and Guide Specifications for LRFD Seismic Bridge Design, 2nd Edition, where applicable. The basics of seismic design principles and seismic design philosophies (force- and displacement-based) are presented and discussed. Earthquake resisting systems and design strategies for bridge systems with integral caps and dropped caps are presented. The earthquake resisting systems for bridges in Seismic Zones 3 or 4 are classified into one of the following two categories : Type 1 – an elastic superstructure with a ductile substructure or Type 2 – an elastic superstructure and substructure with a fusing mechanism at their interface; these are discussed in detail. Design and checks on the seismic forces and displacements for earthquake resisting elements are discussed.
In the second part, emerging information on seismic connection details is presented, and design for ABC, including alternatives in column-footing and column-pier cap connections and segmental columns, is explained. Feasibility of different coupler types and recent large-scale experimental test data are briefly discussed. Emphasis is placed on connections that emulate cast-in-place construction. Recent developments in the application of advanced materials to improve seismic performance of highway bridges are also highlighted. Materials with unique properties such as shape memory alloys, engineered cementitious composites, fiber-reinforced polymer composite tubes and fabrics, and built-in elastomeric segments are discussed along with a demonstration of their performance in large-scale bridge models and components tested on shake tables under simulated ground motions.
