The long-term goal of this project is to understand and mitigate the uncertainties of shallow-water acoustic inversions caused by strong oceanic temporal and spatial variability. To achieve this goal, we need to investigate the connection between acoustic signal fluctuations and the water-column variability, and further incorporate this connection into the acoustic inversions for increasing the...

This article evaluates and compares the punching shear behaviour of unbonded prestressed concrete (UPC) slab - concrete-filled steel tube (CFT) column connections/joints with that reinforced (RC) connection – CFT connections. The experimental program was carried out on five large-sized samples, including three UPC samples two RC samples. Steel plate details were utilised to increase bond betwee...

This paper presents nonlinear elastic dynamic analysis of 3-D semi-rigid steel frames including geometric and connection nonlinearities. The geometric nonlinearity is considered by using stability functions and updating geometric stiffness matrix. The nonlinear behavior of the steel beam-to-column connection is considered by using a zero-length independent connection element comprising of six t...

The SidePlate moment connection system, developed by MNH-SMRF Systems, Inc., looks different because it is different. SidePlateTM's unique trademark geometry provides physical separation between the face of column and end of beam by means of parallel full-depth side plates. This innovative feature ensures the elimination of all brittle behavioral uncertainties responsible for the unprecedented...
