Computational Modeling Of Laminated Veneer Bamboo (Lvb) Dowel Joints, Niloufar Khoshbakht
Computational Modeling Of Laminated Veneer Bamboo (Lvb) Dowel Joints, Niloufar Khoshbakht
Doctoral Dissertations
Laminated veneer bamboo (LVB) is a sustainable building material that has been gaining interest in the construction industry of late. As a relatively new product, little is known about its connection performance, specifically, its failure behavior in dowel type joints and possible similarities it may have to engineered wood products in terms of failure mechanisms. Research is needed to aid in the understanding of LVB dowel connection failure behavior and to quantify the failure mechanism and key factors associated with LVB dowel connection strength. Modeling, as conducted in this research, is a valuable tool to help devise safe standards and …
Behavior Of Negative Stiffness Metamaterial Systems In Structural Engineering Applications, Yasser Darwish
Behavior Of Negative Stiffness Metamaterial Systems In Structural Engineering Applications, Yasser Darwish
Doctoral Dissertations
“Metamaterial systems with negative stiffness behavior became a point of interest in many energy dissipation applications due to their ability to dissipate high levels of energy. Negative stiffness metamaterial elements can dissipate energy through non-linear elastic behavior when transferred from one stable mode of buckling to another. Hence, the ability of such elements to be reusable for multiple loading cycles exists. Such unique properties made the metamaterial systems a perfect candidate for structural applications such as impact protection of bridges against collision. This research provides innovative metamaterial shell structure that can exhibit negative stiffness behavior by deforming from one shape …
