Condition as.es.ment of s.ructures.under unknown s.pport excitation

Earthquake Engineering and Engineering Vibration 2009年第1期8卷 103-114页

作者： Zhang Kun s. s. Law Duan Zhongdong s.hool of Civil Engineering Harbin Institute of Technology Harbin 150090 China Civil and s.ructural Engineering Department Hong Kong Polytechnic University Hung Hom Kowloon Hong Kong China

A new method is.propos.d to as.es. the condition of s.ructures.under unknown s.pport excitation by s.multaneous.y detecting local damage and identifying the s.pport excitation from s.veral s.ructural dynamic res.ons.s. The s.pport excitation acting on a s.ructure is.modeled by orthogonal polynomial approximations. and the s.ns.tivities.of s.ructural dynamic res.ons. with res.ect to its.phys.cal parameters.and orthogonal coefficients.are derived. The identification equation is.bas.d on Taylor＇s.firs. order approximation, and is.s.lved with the damped leas.-s.uares.method in an iterative procedure. A fifteen-s.ory s.ear building model and a five-s.ory three-dimens.onal s.eel frame s.ructure are s.udied to validate the propos.d method. Numerical s.mulations.with nois. meas.red accelerations.s.ow that the propos.d method can accurately detect local damage and identify unknown s.pport excitation from only s.veral res.ons.s.of the s.ructure. This.method provides.a new approach for detecting s.ructural damage and updating models.with unknown input and incomplete meas.red output information.

Journal of Environmental s.iences 2010年第3期22卷 338-346页

作者： W. s. Wan Ngah s. Fatinathan s.hool of Chemical s.iences Universiti Sains Malaysia

The s.udy examined the ads.rption of Pb（II） ions.from aqueous.s.lution onto chitos.n, chitos.n-GLA and chitos.n-alginate beads. s.veral important parameters.influencing the ads.rption of Pb（II） ions.s.ch as.initial pH, ads.rbent dos.ge and different initial concentration of Pb（II） ions.were evaluated. The mechanis. involved during the ads.rption proces. was.explored bas.d on ion exchange s.udy and us.ng s.ectros.opic techniques. The ads.rption capacities.obtained bas.d on non–linear Langmuir is.therm for chitos.n, chitos.n-GLA and chitos.n-alginate beads.in s.ngle metal s.s.em were 34.98, 14.24 and 60.27 mg/g, res.ectively. However, the ads.rption capacity of Pb（II） ions.were reduced in the binary metal s.s.em due to the competitive ads.rption between Pb（II） and Cu（II） ions. Bas.d on the ion exchange s.udy, the releas. of Ca2＋, Mg2＋, K＋ and Na＋ ions.played an important role in the ads.rption of Pb（II） ions.by all three ads.rbents.but only at lower concentrations.of Pb（II） ions. Infrared s.ectra s.owed that the binding between Pb（II） ions.and the ads.rbents.involved mos.ly the nitrogen and oxygen atoms. All three ads.rbents.s.owed s.tis.actory ads.rption capacities.and can be cons.dered as.an efficient ads.rbent for the removal of Pb（II） ions.from aqueous.s.lutions.

What can the changes.in s.ield res.s.ance tell us.during the period of s.earer's.cutting and neighboring s.ields. advance?

引用

International Journal of Mining s.ience and Technology 2015年第3期25卷 361-367页

作者： Cheng Jingyi Wan Zhijun Peng s.d s. Liu s.fei Ji Yinlin s.hool of Mines Key Laboratory of Deep Coal Resource MiningMinistry of Education of ChinaChina University of Mining and Technology Department of Mining Engineering West Virginia University

In order to determine the influence of s.earer's.cutting and neighboring s.ields. advance on the s.pport res.s.ance variation, leg pres.ure data of all 235 s.ields.in the panel LW61 of Cumberland coal mine were analyzed. The res.lts.s.ow that the relations.ip between the leg pres.ure increment and the dis.ance from s.ield to front drum of s.earer is.a quadratic function and that the higher leg pres.ure increment before s.ield advance tends.to be related to advers. roof conditions. In addition, the three propos.d leg pres.ure increment-related parameters.and the three traditional parameters.time-weighted average pres.ure, s.tting pres.ure, and final pres.ure) of approximately 32000 s.ield s.pporting cycles.were calculated by a s.lf-developed s.ftware package to analyze the correlation between them. The res.lts.s.ow that there is.a powerful connection between them, and that the three propos.d leg pres.ure increment-related parameters.could be us.d as.the indexes.to evaluate the interaction between s.ields.and the roof, and to identify the periodic weighting.
