Abstract

fetched live from OpenAlex

Structures made with normal concrete are usually heavy and require considerable quantities of raw materials. For structures made to span large distances, the dimension of the span is usually limited by the weight of the structure itself. In case of UHPC, increased strength lowers the mass to strength ratio providing for more economical deployment of resources. Slender and light structural components which are aesthetically pleasing can made with UHPC without lowering load bearing capacity. UHPC opens up a field of completely new possibilities. However, a disadvantage of UHPC is its cement content which, LIFE CYCLE ASSESSMENT OF UHPC BRIDGE CONSTRUCTIONS: SHERBROOKE FOOTBRIDGE, KASSEL GARTNERPLATZ FOOTBRIDGE AND WAPELLO ROAD BRIDGE

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
