Feasibility Of A Fiber Reinforced Polymer Retrofit For Non-Ductile Concrete Walls, Rory S. De Sevilla, Jerry Hue Truong Luong, Anahid A. Behrouzi, Peter T. Laursen, Mike J. Deigert Aug 2019

Feasibility Of A Fiber Reinforced Polymer Retrofit For Non-Ductile Concrete Walls, Rory S. De Sevilla, Jerry Hue Truong Luong, Anahid A. Behrouzi, Peter T. Laursen, Mike J. Deigert

Architectural Engineering

A significant number of pre-1980’s non-ductile reinforced concrete (RC) structures in California have been identified as deficient, many of which utilize RC shear wall systems to resist earthquake lateral forces. These non-ductile wall systems are typically lightly reinforced and lack adequate boundary element detailing. Engineers suspect these walls to susceptible to brittle, compression-controlled failure modes due to damage from concrete crushing and bar buckling. As a result, one approach designers are taking is to seek fiber reinforced polymer (FRP) retrofit solutions that improve the compression capacity of high-stressed wall end zone regions based on effectiveness of these approaches with ...

Topology And Form Finding Via Genetic Algorithms, Michael Goldenberg, Nick Coburn Jun 2019

Topology And Form Finding Via Genetic Algorithms, Michael Goldenberg, Nick Coburn

Architectural Engineering

The following presents an approach to early applications of the Galapagos program as a means to optimize structural forms. The process was conducted with Rhino’s Grasshopper program, the structural analysis plug-in, Karamba, and the genetic algorithm solver, Galapagos. This topological form finding process was based on flexible parameters that modified brace and column locations, and diaphragm size and positions.

This process worked by having Galapagos modify a parametric model which had initial randomly generated variables for the genomes. After structural analysis, Galapagos was tasked with changing the form in order to minimize overall displacement of the structure. Being an ...

Clt Shearwall Dovetail Connection, Alexander Eduardo Esser, August Messano Dec 2018

Clt Shearwall Dovetail Connection, Alexander Eduardo Esser, August Messano

Architectural Engineering

As cross-laminated timber has become an increasingly popular construction material, its use as a shear wall element has also demanded attention. Primary obstructions to the use of CLT shear walls have been the lack of an economic connection type that does not compromise the structural integrity and has the robustness that CLT shear wall panels deserve. Dovetail connections provide a great option for the connection of CLT shear walls. With more experimentation, the optimal dovetail geometry can be further developed. The small-scale testing done in conjunction with this report proved that very deep pins and tails will result in bearing ...
