A review of the research on the lateral force resistance of cold-formed shear wall

IOP Conference Series: Materials Science and Engineering, 2020
Abstract In this paper, the research on the lateral force resistance of the existing cold-formed thin-walled steel shear wall was briefly summarized. The innovation of the new cold-formed thin-walled steel composite wall proposed in recent years and the improvement of the existing structure system were described.

Shear critical R/C columns under increasing axial load [PDF]

, 2020
Structural elements in old reinforced concrete (R/C) frame buildings are often prone to shear or flexure-shear failure, which can eventually lead to loss of axial load capacity of vertical elements and initiate vertical progressive collapse of a building.

Development of a novel lateral resistance measurement penetrometer for pipe–soil interaction centrifuge model test

International Journal of Distributed Sensor Networks, 2018
Offshore pipelines are exposed to potential submarine landslides. It is difficult to measure the impact forces exerted on a pipeline induced by submarine landslides because the upper seabed is very soft and an impact angle exists in practice.

Lateral migration resistance of screw is essential in evaluating bone screw stability of plate fixation

Scientific Reports, 2021
Conventional evaluation of the stability of bone screws focuses on pullout strength, while neglecting lateral migration resistance. We measured pullout strength and lateral migration resistance of bone screws and determined how these characteristics ...

Self-Centering Seismic Lateral Force Resisting Systems: High Performance Structures for the City of Tomorrow [PDF]

Buildings, 2014
Structures designed in accordance with even the most modern buildings codes are expected to sustain damage during a severe earthquake; however; these structures are expected to protect the lives of the occupants. Damage to the structure can require expensive repairs; significant business downtime; and in some cases building demolition. If damage occurs
