Shrinkage Cracking In Concrete Tilt-Up Construction, Stewart Hooks, Jack Robinson

Architectural Engineering

The purpose of this project is to investigate a particular, undesirable cracking pattern in concrete tilt-up panels that, until now, did not have a known definite cause. The cause of this cracking pattern is hypothesized to be due to shrinkage restraint of the concrete panels. The cracking under investigation occurs at the bottom corners of the Tilt-Up panels, suggesting that the base of the panel is restrained from shrinkage. This project models various components of Tilt-Up Construction that have potential for restraining the panels from shrinking. This project consists of the following main components.

Fluid Isolator, Purdue Ect Team

ECT Fact Sheets Archive

The reliability of concrete infrastructure is vital to ensuring daily life, as well as commerce, can progress without interruption. From the pavement of interstate highways to the driveways and sidewalks in a local neighborhood, concrete is expensive to install and often even more expensive, and intrusive, when it needs to be replaced. Unfortunately, to maintain functionality in winter climates concrete is heavily exposed to deicing salts. This not only affects the roads, driveways, and sidewalks where salt is applied directly, but many other areas such as parking and residential garages where vehicles (and people) will track salt along with water …

Implementing Online Updating To Complex Hysteresis Models In Real- Time Hybrid Simulation Using Constrained Unscented Kalman Filter, Bilal Ahmed Mohammed

Masters Theses

Although conventional experimental methods, such as quasi-static testing, shake table testing, etc., perform well to evaluate structural seismic performance necessary for modern seismic design, the quasi-static loading and/or reduced scale specimen used in shake table testing may not provide true dynamic responses of structural systems. To overcome these limitations, real-time hybrid simulation (RTHS) was developed, which is a combination of physical testing of the experimental substructure and analytical simulation of the numerical substructure. With the advancement of hybrid simulation, it is now possible to economically test large to full-scale specimens in laboratories at the real earthquake rate. Online model updating …
