The finally adopted bridge concept was a two- main-span continuous suspension bridge supporting the future 4-lane road connection the paper is also concerned with the implications of the seismic demand, in terms of special design of. For years, the seismic concerns of legislators and building design professionals were limited primarily to structure-related life-safety issues that changed after an earthquake considered moderate in seismological terms caused death and widespread destruction in san fernando, calif, feb 9, 1971.
Like chapter 5, this chapter is devoted exclusively to the seismic design of new buildings it emphasises the importance of the layout of the structural system for the building’s seismic performance and highlights the principles to be followed and the pitfalls to be avoided during the initial stage of the design process, notably during conceptual design. Seismic sections of this course are now covered by the seabc e12 (seismic design of steel structures) and this course will concentrate on the non-seismic portions of seismic design and additional non-seismic material will be added to replace the seismic sections now covered in e12. According to the framework of performance-based design (seaoc 2000 ), single or multiple performance objectives are selected at first according to seismic design code and the requirement of the owner in the conceptual design phase.

Figure 1—the seismic design maps in the 2012 irc targeting concept, several other changes made to the ibc maps in 2012 also contributed among these was the incorporation of updated data via the latest (2008) seismic hazard computations produced by the.
Even the cleverest calculations and detailed design cannot compensate for errors and defects in the conceptual seismic design of the structure or in the selection of non-structural elements, in particular partition walls and facade elements. Concepts of seismic-resistant design this topic introduces the concepts of seismic-resistant design from a philosophical perspective for this reason, design examples design concepts 7 - 2 1 develop concept (design philosophy) 2 select structural system 3 establish performance objectives 4. Conceptual seismic design is a qualitative design for seismic performance of the structure, and the corresponding design is the quantitative design based on seismic response analysis.
