(0.25+ KUA where L = reduced design live load per ft' (m) of area supported by the member L = unreduced design live load per it' (m) of area supported by the member (see Table 4-1) Ku = live load element factor (see Table 4-2) A = tributary area in It (m) I shall not be less than 0.50L for members supporting one floor and I shall not be less than 0.40L, for members supporting two or more floors. Analysis and design of slab resting directly on masonry walls. Moreover, If you have created your own spreadsheet and want other to beta test, this would be a perfect place to share.
Show free body diagrams for a typical interior joist, interior girder, interior spandrel and interior columnĤ.7.2 Reduction in Uniform Live Loads Subject to the limitations of Sections 4.7.3 through 4.7.6, members for which a value of K, A, is 400 Ft (37.16 m') or more are permitted to be designed for a reduced live load in accordance with the following formula: ) L=2.0.25+_15 (4.7-1) " K, A, In SI: 4.57 L = L. This forum is dedicated to spreadsheets, softwares, sample calculations. For each case, show how the tributary loads are computed using free body diagrams 5. Use the combination 1.2DL+1.6LL to find the design fotored louds 4. Assume four numerical grid lines along the length of the mezzanine and three alphabetical across 3. Draw a floor plan with a grid system in both directions 2. Secondary girders coincide with the location of the major grid lines 1 thru 4. The primary girders are supported by secondary girders at 22ft on center.
Primary girders run along the length of the mezzanine. While calculating for bending, to include shear deformation or not is again based on option Not sure about surface, may be it is just to transfer. The joists are supported by primary girders spaced at 12.5ft on center. Answer: In general plate element can calculate bending moment and not in-plane forces Shell element can calculate both bending and in-plane forces. Joists run along the width of the mezzanine. The floor is supported on joists spaced at 2ft on center. The spacing of the column across the width of the mezzanine is 25ft. The spacing of the columns along the length of the mezzanine is 22ft on center. Assume the dead load is 65psf which includes the self- weight of the members. Using a load combination 1.2DL+16LL analyze a typical interior joist, interior primary girder, interior secondary girder and the interior column. of the lake dwellers, driven more than 2000 years ago are still intact.
Integrated design code features can automatically generate wind, wave, bridge, and seismic loads with comprehensive automatic steel and concrete design code checks per US, Canadian and international design standards.Transcribed image text: Problem 1 Analysis of Beams and Frames - First Order Analysis (100 pts.) You are required to analyze the mezzanine system shown in Figure 1.1 for gravity loads. For sawed stock the method of rift or quarter sawing, which has so. Detailing and Design of One way Ribbed slab using etabs tutorialETABS Reinforcement formula. Now you can harness the power of SAP2000 for all of your analysis and design tasks, including small day-to-day problems.Ĭomplex Models can be generated and meshed with powerful built in templates. Two Way Joist Concrete Waffle Slab Floor Design Detailing. This intuitive interface allows you to create structural models rapidly and intuitively without long learning curve delays.
SAP2000 follows in the same tradition featuring a very sophisticated, intuitive and versatile user interface powered by an unmatched analysis engine and design tools for engineers working on transportation, industrial, public works, sports, and other facilities.įrom its 3D object based graphical modeling environment to the wide variety of analysis and design options completely integrated across one powerful user interface, SAP2000 has proven to be the most integrated, productive and practical general purpose structural program on the market today. The SAP name has been synonymous with state-of-the-art analytical methods since its introduction over 30 years ago. The file format used ends in the three-letter extension S2K. Structural Desktop uses an input file for SAP 2000 from Computers & Structures, Inc.
