Conclusions

Significant cost savings can be realized by conducting the more rigorous Equivalent Lateral Force procedure for structures allowed to be analyzed by the Simplified procedure. 2. The Simplified procedure is not worthwhile in practice due to use restrictions and over-conservative base shear values. 3. Negligible cost savings is realized by conducting the more rigorous Modal Response Spectra procedure for structures less than five stories. 4. The Modal Response Spectra procedure will not result in...

Case Study Telephone Coop Office Building

The first structure is a single-story office building with sloped metal standing seam roofs. The roofs bear front and back at differing elevations and slope to approximately the center of the building at differing slopes forming a vertical face where clerestory windows are located indirectly lighting select offices. Figures 3.1 through 3.4. Figure 3.5 shows an architectural cross section of the building depicting the roof slopes and the clerestory windows. Figure 3.6 shows an architectural...

Info

S Simplified Analysis procedure ELF Equivalent Lateral Force procedure Three additional items had to be designed for the lateral-force resisting system of this structure. First, the moment resisting connections for the joists and the joist girders had to be designed. There is a division of responsibility for these connections. The structural engineer is responsible for providing the column cap plate (for joists) and seated connection (for joist girders), welding requirements, the continuity...

Chapter

OBJECTIVE, INTRODUCTION AND BACKGROUND The International Building Code is quickly becoming the definitive standard for construction throughout the United States. This code is replacing regional codes, being used in most federal construction, and is being adopted for state construction projects and projects in numerous municipalities. Due to the fact that the International Building Code typically produces significantly higher seismic forces than the Southern Building Code (SBC) or the Uniform...

Code Procedure for Seismic Design Category A

Structures determined to be in Seismic Design Category (SDC) A are required to comply only with the provisions of Section 1616.4 1 . There are five exceptions to this rule. First, detached Group R-3 dwellings in SDC A, B, and C are exempt from the general seismic provisions. Detached one- and two-family dwellings and multiple single-family dwellings (townhouses) not more than three stories high with separate means of egress and their accessory structures shall comply with the International...
