Bending theory of Vierendeel Sandwich Plate based on variational method

Dingyuan Liu et al.

Summary: The mechanical principle of the Vierendeel Sandwich Plate is to reduce the dead weight of the structure by excavating the web of the thick plate evenly. It is suitable for large span building roof structures and is composed of surface plate, upper rib, lower rib, and short column. The governing equations of the Vierendeel Sandwich Plate are established using the variational method and Lagrange multipliers. An example is given to verify the feasibility and accuracy of the proposed method, showing that the existing solutions for single layer and multi-layer sandwiches can be extended to the Vierendeel Sandwich Plate by considering the membrane force and redefining the physical constants.

Effect of blast loading and resulting progressive failure of a cable-stayed bridge

Ravi Mudragada et al.

Summary: This study evaluated the robustness and resistance of the Charles River Cable-Stayed Bridge in Boston against blast loads through a case study. Findings suggest that the bridge is at risk of progressive collapse near the tower location under excessive blast loads, indicating a need for strengthened structural components to prevent collapse.
