Mountains in the Sea: Round and Round [PDF]
In this activity, students will explore circulation cells in the vicinity of seamounts. They will be able to interpret data from a three-dimensional array of current monitors to infer an overall pattern of water circulation, hypothesize what effect an ...

Structural Concrete, EarlyView.Abstract The accurate prediction of the shear capacity of reinforced concrete underpins the efficient and safe design of concrete buildings and infrastructure. Disagreement remains about shear mechanisms and the modeling of shear resistance. For slender beams without shear reinforcement, critical shear crack (CSC) models have attracted interest.

Enhancement of shear strength of bonded post-tensioned beams using inverted-U shaped reinforcements
Case Studies in Construction Materials, 2020 At cracked stage, the post-tensioned concrete beams resist shear through a different set of mechanisms, the accepted mechanisms are: interface shear transfer, dowel action of longitudinal reinforcements, shear transfer in compression zone, transversal ...

Incremental upper bound modeling of concrete failures in timber‐concrete notched connections
Structural Concrete, EarlyView.Abstract This paper introduces a novel theoretical framework for developing incremental upper bound solutions, which is applied to predict the response of two local concrete failures in timber‐concrete composite (TCC) decks with notched connections. The new approach enables a prediction of the capacity at the onset of failure as well as the entire post‐

Nonlinear analysis of flat post‐tensioned concrete slab–edge column connections
Structural Concrete, EarlyView.Abstract This study presents nonlinear finite element analyses to investigate the punching shear behavior of unbonded post‐tensioned concrete flat slabs at slab‐edge column connections. A parametric analysis was conducted to evaluate the influence of four critical parameters on the punching shear resistance: the distribution of prestressing tendons ...
