The Newmark Structural Engineering Laboratory (NSEL) has both <\/span>Manually-Controlled and Servo-Controlled hydraulic equipment<\/strong>\r\n . Manually-controlled hydraulic equipment includes hydraulic actuators with capacities ranging from 10 to 150 tins (11 to 330 kips) and strokes ranging from 5 to 22 inches (127 to 559 mm). These actuators can be supported by electric\r\n and manual pumps. Servo-controlled hydraulic equipment has nominal ratings ranging from 2.5 to 230 (11 to 1,000 kN) and strokes ranging from 6 to 20 in (152 to 508 mm). These are supported by Hydraulic Power Supplies with a pressure\r\n of 3000 psi (20.7 MPa) and an oil flow rate of up to 180 gpm (680 l\/min). <\/span>MTS and Instron controllers<\/strong> are also available to drive these actuators. Any mode of control (position, load, strain, external transducer) can be applied. Auto-tuning and adaptive control options are available in these controllers as well. <\/span><\/p>\r\n Moreover, NSEL is equipped with fatigue-rated testing frames. The load capacity of these frames range from 20 to 600 kips (89 kN to 2.7 MN). NSEL can provide <\/span>\r\n instrumentation <\/strong>to support any type of transducer (LVDTs, Strain Gauges, Load Cells, Accelerometers, etc.) as well. There is also a wide range of hardware (columns, I-Beams, Channels, etc.) that allow to conduct full-scale tests of structures. <\/span><\/p>\r\n \r\n
