STEM Student Research Symposium Posters

Every year AISC runs a regional and national steel bridge competition. The competition offers a chance for civil engineering students to gain valuable experience designing a bridge. In addition to this, mechanical engineering students are provided the opportunity to practice machining steel parts. For the competition, teams from participating schools are given a scenario with certain constraints to design a bridge for. At the competition, the bridges are ranked based on weight, structural efficiency, construction economy, assembly speed, deflection, aesthetics, and overall performance.

The program Risa 3D was used in order to design and perform analysis on the bridge. Using …

Application of Computational Tools to Spaghetti-Based Truss Design

Statics and Strength of Materials are two foundational courses for Mechanical/Civil Engineering. In order to assist students in better understanding and applying concepts to a meaningful design task, SolidWorks and theoretical calculation were used for a spaghetti-bridge design contest with the constraints of given maximum weight and allowable support-material weight. As the first step of this iterative designing process, both extrude feature and structural member were introduced to model planar bridge trusses. Then SolidWorks’ Statics module was used to run FEA analysis of the structural performance in efforts to optimize the …

Use Of Penetrating Asphalt Emulsions To Address High-Void Pavement Areas, Andrew Eicher, Curt Higginbotham

Purdue Road School

Longitudinal joints are high in air voids due to compaction limitations. Lowering the void content of these areas improves the durability of the pavement. Project data indicate that rapid penetrating emulsion (RPE) fills the voids beneath the surface of the pavement, reducing air and water intrusion while maintaining surface texture, whereas traditional emulsions seal the surface only. Lab tests have been developed to quantify the penetrating ability of an emulsion and resistance to water exposure. Join us for a discussion.
