The load capacity of laterally restrained reinforced concrete one-way slabs currently is estimated by entering the compressive membrane theory with a midspan deflection. However, the midspan deflection estimates exhibit large variability. The point of peak thrust is a more accurate index of the peak load capacity, than midspan deflection estimates and even experimentally measured midspan deflections. The calculation of the thrust within the compressive membrane theory is a maximum when ...
This document describes progress on the project, PET Studies of Components of High-Level Vision (N00014-91-J-1243). We have made progress primarily by testing more subjects in four PET experiments, developing new software for data analysis, and carrying out preliminary data analyses. It is premature to report the results in detail, but some intriguing trends are evident in the images, as noted in this report.
