The long-awaited 2nd Edition of AISC's Design Guide 11 (DG11) was made available in 2016. This article will summarize the changes relating to Chapter 6: "Design for Sensitive Equipment and Sensitive Occupancies" and the corresponding portions of Chapter 7 relating to the same topic.
Kerri Stein handles accounting and office administration tasks at ESI.
ESI recently presented "Noise Basics, Measurement and Requirements" at the Annual Institute for Building Officials at the University of Minnesota on January 12th, 2017.
Andrew Schmitt will be serving as a Consulting Engineer in Noise Control and Acoustics. Passionate about acoustics, noise control, and problem-solving, he is a great fit to the ESI team.
ESI is pleased to welcome Arjun Shankar as an Intern in Noise Control and Acoustics this summer. Arjun will be working closely with Tony Baxter and Ryan Skoug on measurements, data analysis, calculations and reports.
The CRSI has issued a new guide to vibrations of reinforced concrete floor systems. This guide aims to provide a simplified design method for the design professional and general guidelines on how to mitigate vibration issues in new and existing buildings.
Learn about wall STC ratings and what to look for to make sure your design is the best it can be. Improvements to the noise control performance, and ultimately cost, of wall assemblies depend on many factors some of which may seem counter-intuitive.
Learn about the traps found when performing footfall vibration analysis for buildings and how to avoid them. This topic is of interest to architects or structural engineers designing buildings used for laboratories, imaging, wafer fab, or other vibration sensitive occupancies.
We are excited to announce that ESI will be presenting on vibration design of equipment foundations for dynamic loads to control vibration at the University of Minnesota Department of Civil Engineering on October 30th, 2015.
Madeline Davidson will be working with ESI on noise control and acoustics projects this summer.
An electrodynamic shaker is used to help solve real world problems involving vibration of floors and footbridges. They use electrical current and magnets to oscillate a heavy piston up and down at a specific frequency, or range of frequencies, as controlled by an amplifier.
ESI provided vibration engineering consulting for the cantilever balconies in this massive renovation effort.
Our focus will be on controlling vibration and noise for the regional hospital with a vision of “A place of extraordinary care…delivered with the view of innovation, compassion and understanding.
