Research on Flexural Performance of Truss-Reinforced Composite Slabs with a Single Rectangular Rib

Truss-reinforced concrete composite slabs (TRCs) are extensively applied in prefabricated construction, but the limited stiffness of precast base plates may lead to excessive deformation and cracking during construction. This study investigates the truss-reinforced concrete compo...

Four Layers of Negativity in the Rei Stack: A Structural Framework for When a Minus Sign is a Failure, a Target, a Theorem, or a Notation

We identify and separate four layers on which a minus sign appears in the Rei-AIOS software stack. This is a test v0.2 minimal-metadata deposit to bisect the HTTP 500 issue.
