AbstractThe objective of the present study is to investigate numerically, the effect of table size on the roofing system response. A commercially available Finite Element program, ABAQUS version 5.8, with non-linear analysis capability was used to carry out all the analyses. Details of the adopted model, benchmarking of the developed model with experimental data and procedure used to derive correction factors are reported by Baskaran, A., Zahrai, S. M. and Chen, Y in a technical paper entitled, "Numerical Evaluation of Roofing Systems for Wind Uplift Pressures'. This report archives all the results for the fastener loads obtained from the numerical analyses. Thermoplastic assemblies with TPO and PVC membranes were considered. To study the effect of table size, simulations were performed for the variations of the two influencing factors, namely, fastener row spacing (Fr) and fastener spacing (Fs). Three Fr, configurations 1830, 1700 and 1220 mm (72", 67" and 48) with three Fs, configurations 152,305 and 460 mm (6, 12" and 18) were considered. Fifteen simulations were performed for each configuration by varying the table width. Computed fastener loads are given in Tables 2 to 5. In highlighted form, Appendix A provides examples of input files with the respective output files. Coordinates of the all the required files for the presented simulations are tabulated in Appendix B.
