Henan malpractice Construction Engineering Testing Co., Ltd. is a professional testing company, is one of the qualification place in Henan Province since the first detection through examination of business. Business in the Pile qualification qualification, the qualification grade steel, a qualified indoor environment, building energy efficiency testing, subject testing, materials testing, glass curtain wall testing, roads and bridges detection, detection of a number of civil air defense projects testing qualification and testing laboratories. Quasi dynamic testing, also known as computer - loader online test, calculation and control and structural testing will computers together organically, that is, from a given seismic acceleration curves through computer analysis of nonlinear dynamic Luoyang steel detection, The calculated displacement data as input to control the structure of the loader to load, so a detection method for real-time simulation earthquake response can be achieved in a static test bench. While the pseudo-dynamic testing the loading process is quasi-static, but it pseudo static detection methods are essentially different: pseudo-static load test each step goal (displacement or force) is known, but the proposed dynamic testing Each step load goal is to measure and calculate the results of the previous step by recursive formula based on the discrete dynamic equation test structure was established. Therefore, the proposed dynamic test without prior assumed resilience characteristic structure, by a computer to perform nonlinear seismic response of differential equations, and the restoring force value is measured by direct action on the loader loads the measured object worth to. Henan malpractice Construction Engineering Testing Co., Ltd. is a professional testing company, is one of the qualification place in Henan Province since the first detection through examination of business. Business in the Pile qualification qualification, the qualification grade steel, a qualified indoor environment, building energy efficiency testing, subject testing, materials testing, glass curtain wall testing, roads and bridges detection, detection of a number of civil air defense projects testing qualification and testing laboratories. The task of the project is to detect structure by detecting or observing instruments and equipment Yanshi steel structure testing, testing in accordance with relevant technical regulations and standards, there are plans to use the appropriate means, for engineering structures or components in certain loads (such as gravity, mechanical Interferences, seismic force, wind, etc.) or other factors (such as temperature, deformation settlement, fire, etc.) performance under the action of observation and measurement, and draw relevant parameters (such as deformation, deflection, displacement, angle, strain amplitude, frequency, etc.), and its processing and analysis. The purpose of the project is based on the measured structure detection results and related appraisal standards, capacity, safety stock and stiffness, crack resistance and other engineering structures or members make a correct estimation and evaluation; or to test a number of engineering structures and new materials The new system, new technology and technical indicators of the performance is in line with the relevant standards to provide reliable scientific basis for assessment.
