Sample Writing
Sample taken from the final project report “4A Engineering Report on CareAmerica, Hilo, Hawaii” in Dr. James Jirsa’s Earthquake Engineering course, Fall 2012
With the given dead and live load, our pan joist calculations began by calculating the moment demand. ACI moment coefficients from section 8.3.3 were used to get the final load. The most critical load for interior and exterior spans was used for easy of design. This allows us to design for constant reinforcement throughout the typical interior floors. Treating the joist as a T-beam, the loading resulted in the compression block contained within the flange resulting in easier analysis. The final design of the joist is repeated every 30” on center and is shown below (Figure 3).
Figure 3. Typical Pan Joist (Floors 1-4)
Checks for proper strain in the reinforcing steel were done. In addition, based on the ACI 21.13 code for non-lateral load gravity members, the joist section required two continuous bars. This far exceeded the required steel area so it controlled the design process. The detailed calculations and values for the moment calculations can be found in Appendix C.1.
The comparatively large area of the pan joist compared to the low loading meant shear was nearly inconsequential. Benefitting from ACI 8.18.8, the concrete shear resistance was increased by 10%, nearly providing 0.5φVn. One stirrup was required though, and is placed at one half the effective depth of the joist. This value was rounded down to the nearest integer resulting in s = 7in.
