ANCO Engineers, Inc. Information

ANCO Engineers provides our clients with vibration testing equipment and services, including single- and multi-axis shake tables, field vibration testing and vibration reduction, and eccentric mass vibrators for modal testing of full-scale civil structures in the field. Our earthquake shake tables provide uni-axial, bi-axial, or tri-axial motion for testing equipment and structures in University research laboratories and commercial testing laboratories. Tables can accommodate payloads between 10 and 50,000 kg. Our various shake table models can also simulate transportation vibration and high-frequency shock and vibration. Our field testing measures the dynamic properties of structures and quantifies unwanted operational vibration and offers vibration reduction designs and equipment. Our eccentric mass vibrators can excite small to large civil structures and determine their modal properties such as resonant frequencies, damping, and mode shapes, as well as characterizing non-linear phenomena and tracking structural degradation over time.
