Ordinance No. 1894 Page 3 California provided hundreds of examples of damage to buildings of light frame construction. The poor soil that these foundations must rely on to hold up buildings is of vital importance to constructing a building. It is sensible then that the seismic provisions for structural steel buildings be the most up to date national standards. It is imperative for a city, like the City of Pleasanton, in seismic zone 4 to require that the design methods for load and resistance factor design (LRFD), deformation compatibility, basic, vertical and alternate load combinations, horizontal distribution, horizontal torsional moments and story drift as well as allowable stress design be of the highest standard followed among the most current national standards. WHEREAS, the City Council finds that because of the reasons stated, the State of California adopted Building Standards Code, Specifications, and Standards in their entirety do not adequately address the life safety requirements of the City of Pleasanton; and WHEREAS, the City Council finds that because of the local topography and recent seismic activity and pursuant to Health and Safety Code Section 18941.5, the requirements of the Pleasanton Municipal Code Section 20.08.056, the codes and standards of this Ordinance are necessary for the health, safety and welfare of the residents of the City of Pleasanton; THE CITY COUNCIL OF THE CITY OF PLEASANTON DOES HEREBY ORDAIN AS FOLLOWS: Section 1.

When the load combinations from Section 1612.2 for LRFD are used, structural steel buildings shall be designed in accordance with Chapter 22 Division II (AISC-LRFD) and Part I of AISC- Seismic as modified by this Division. When the load combinations from Section 1612.3 for ASD are used, structural steel buildings shall be designed in accordance with Chapter 22 Division HI (AISC-ASD) and Part III of AISC-Seismic as modified by this Division.
