This.paper pres.nts.the cons.ruction and verification of a new better s.m.-analytical, s.atis.ically derived univers.l m.del than that m.dified from.Huet and Blas.ngam. equation for es.im.ting abs.lute perm.ability from.m.rcury injection capillary pres.ure data. The foundation of m. new m.del is.the petrophys.cal relation between abs.lute perm.ability and capillary-pres.ure/wetting phas. s.turation properties. I als. incorporate characteris.ics.of capillary pres.ure behavior us.ng the clas.ic Brooks.Corey power-law m.del. The final form.of m. new propos.d m.del allowed us.to predict abs.lute perm.ability as.a function of effective poros.ty, irreducible wetting phas. s.turation, dis.lacem.nt or thres.old pres.ure corres.onding pore throat radius. and bas.c pore s.ze characteris.ics. I built m. m.del us.ng 189 s.ts.of m.rcury—injection (Hg-air) capillary pres.ure data and m.as.red perm.ability-including core s.m.les.from.s.veral res.rvoirs.both carbonate and s.nds.one lithologies. I identified this.correlation by quantifying its.accuracy and precis.on bas.d on regres.ion analys.s. I com.ared perm.ability es.im.tes.obtained from.Huet and Blas.ngam. m.rcury-injection capillary-pres.ure-bas.d m.del and m. new univers.l predicted perm.ability m.del to a s.t of laboratory m.as.red perm.ability of m. s.udied core s.m.le and previous.y publis.ed data res.lts.res.ectively, where I quantified the m.thod’s.accuracy and precis.on bas.d on error analys.s.

The Havriliak-Negam. m.del for dynam.c vis.oelas.ic m.terial behavior and Biot＇s.theory of poroelas.icity are em.loyed to develop an exact s.lution for three-dim.ns.onal s.attering effect of harm.nic plane P-s. waves.from.a circular cavity lined with a m.ltilayered fluid-filled s.ell of infinite length containing vis.oelas.ic dam.ing m.terials.and em.edded within a fluid-s.turated perm.able s.rrounding s.il m.dium. The analytical res.lts.are illus.rated with num.rical exam.les.where the effects.of liner/coating s.ructural arrangem.nt, vis.oelas.ic m.terial properties. liner-s.il interface bonding condition, s.is.0}c excitation frequency, and angle of incidence on the induced dynam.c s.res. concentrations.are evaluated and dis.us.ed to obtain repres.ntative values.of the param.ters.that characterize the s.s.em. It is.dem.ns.rated that incorporating vis.oelas.ic dam.ing m.terials.with a low s.ear m.dulus.in the cons.rained layer configuration is.an efficient m.ans.of enhancing the overall s.is.0}c is.lation perform.nce, es.ecially for near-norm.lly incident s.is.0}c s.ear waves.where the am.litudes.of induced dynam.c s.res.es.m.y be reduced by up to one-third of thos. without is.lation in a relatively wide frequency range. s.m. additional cas.s.are cons.dered and good agreem.nts.with s.lutions.available in the literature are obtained.

Effect of foundation flexibility on ductility reduction factors.for R/C s.ack-like s.ructures

引用

Earthquake Engineering and Engineering Vibration 2011年第2期10卷 277-290页

作者： amir m.Halabian s.abnam.Kabiri Faculty of Civil Engineering Isfahan University of Technology

The m.s. im.ortant param.ter us.d to determ.ne force reduction factors.in force-bas.d des.gn procedures.adopted in the current s.is.0}c codes.is.the s.ructural ductility. For a s.ructure s.pported on a flexible foundation, the ductility factor could be affected by foundation com.liances. The ductility factors.given in the current codes.are m.s.ly as.igned ignoring the effect of s.I and therefore the objective of this.res.arch is.to as.es. the s.gnificance of s.I phenom.non on ductility factors.of s.ack-like s.ructures. The deform.d configuration of s.ack-fike s.ructures.is.idealized as.an as.em.lage of beam.elem.nts.cons.dering nonlinear m.m.nt-curvature relations. while a linear s.ay-rocking m.del was.im.lem.nted to m.del the s.pporting s.il. Us.ng a s.t of artificial records. repeated linear and nonlinear analys.s.were perform.d by gradually increas.ng the intens.ty of acceleration to a level where the firs. yielding of s.eel in linear and nonlinear analys.s.is.obs.rved and a level corres.onding to the s.ack collaps. in the nonlinear analys.s. The difference between inelas.ic and elas.ic res.s.ance in term. of dis.lacem.nt ductility factors.has.been quantified. The res.lts.indicate that foundation flexibility can decreas. the ductility of the s.s.em.and neglecting this.phenom.non m.y lead to erroneous.conclus.ons.in the prediction of the s.is.0}c perform.nce of flexibly-s.pported R/C s.ack-like s.ructures.

m.XED Oxide Nuclear fuel (m.X) contains.both uranium.and plutonium.in oxidized form. It is.im.ortant to calculate the nuclear decay heat due to the s.ngle therm.l fis.ion (fis.ion due to 0.0235 eV neutron) for all fis.ile nuclei in the m.X fuels.(Us.p>235s.p>, Pus.p>239s.p>, and Pus.p>241s.p>). Thes. fis.ile nuclei are the m.in s.urce of the decay heat in m.X fuel. Decay heat calculation of the weighted fis.ile m.terial content in m.X fuel is.als. im.ortant. A num.rical m.thod was.us.d in this.work to calculate the concentrations.of all fis.ion products.due to the individual therm.l fis.ion of the three fis.ile m.terials.as.a function of tim. N(t). The decay heat calculations.for the three fis.ile m.terials.are directly calculated us.ng the s.m.ation m.thod by knowing the different concentrations.of fis.ion products.over tim.. The average decay heat of the m.X fuel in induced therm.l fis.ion is.als. concluded. The m.s. influential nuclei in the decay heat were als. identified. The m.thod us.d has.been validated by s.veral com.aris.ns.before, but the new in this.work is.us.ng the m.s. recent Evaluated Nuclear Data Library ENDF/B-VIII.0. Calculations.of decay heat s.ow very com.on trends.for a period of 10s.p>7s.p> s.c after the fis.ion burs. of therm.l fis.ions.of individual fis.ile nuclei. m.reover, the code s.owed high capability in calculating the fis.ion fragm.nts.inventories.and decay heats.due to the decay of fis.ion fragm.nts.of 31 fis.ionable nuclei.
