Abstract
A series of shear loading tests were carried out on 14 panel specimens that had various layouts of diaphragms, shear connectors or full-webs, taking a practical example of the critical portion of members on a shear design in the Kobe Minatojime immersed tunnel into consideration. In particular, the panel specimens included 7 of them that had not only diaphragms but also a full-web. Behavior of the panels did not coincide with beam theory based on continuum mechanics but agreed with a truss analogy.
