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. For structural steel truss top set of concrete structures and steel columns, norms have not given the appropriate design. This requires design unit carefully, carefully analyzed. According to the analysis of the project, the following basic requirements: (1) must be considered in combination effect of the earthquake and wind loads, were members bearing capacity checking. ① in the design of concrete structures must be top of the steel structure and a lower structure as a whole earthquake analysis; at least take the time to analyze press Mode Decomposition Method 5 modes; ② and top steel columns have also envelope envelope structure as a skeleton, we must analyze the impact of the top steel columns envelope wind loads; ③ high-rise buildings should be asked to consider the effect of a combination of the design earthquake and wind loads were checking component capacity. 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. This filler dispersion type packed column packed column is coated with a high-boiling organic solvents (such as isotridecanoic) inert porous particles (such as diatomaceous earth), similar to a GC column stationary phase, but an organic solvent use ratio chromatographic stationary phases big. Sampling, the gas sample through a packed column, pile engineering testing, in an organic solvent (stationary phase) distribution coefficient of components remain in the filler is enriched. Such as coated with 5% glycerol silicate carrier do solid adsorbent can put air dieldrin (dieldrin), DDT, polychlorinated biphenyls (PCB) and other pollutants entire retention, sampling efficiency up to 90% to 100%. After enrichment, eluted with methanol sorbate, Anyang County Loess Engineering, with n-hexane purified and concentrated sample, and then measured with electron capture identification, detection limit PCB is 0002mg / m3.
