Buckling rest.ained knee braced t.uss moment.frame （BRKBt.F） is a novel and innovat.ve st.el st.uct.ral syst.m t.at.ut.lizes t.e advant.ges of long-span t.usses and dedicat.d st.uct.ral fuses for seismic applicat.ons. St.el t.usses are very economical and effect.ve in spanning large dist.nce. However, convent.onal st.el t.usses are t.pically not.suit.ble for seismic applicat.on, due t. it. lack of duct.lit. and poor energy dissipat.on capacit.. BRKBt.F ut.lizes buckling rest.ained braces （BRBs） as t.e designat.d st.uct.ral fuses t. dissipat. t.e sudden surge of eart.quake energy. t.is allows t.e BRKBt.F t. economically and efficient.y creat. large span st.uct.ral syst.ms for seismic applicat.ons. In t.is paper, a prot.t.pe BRKBt.F office building locat.d in Berkeley, California, USA, was designed using performance-based plast.c design procedure. t.e seismic performance of t.e prot.t.pe building was assessed using t.e st.t.-of-t.e-art.finit. element.soft.are, OpenSees. Det.iled BRB hyst.resis and advanced element.removal t.chnique was implement.d. t.e modeling approach allows t.e simulat.on for t.e force-deformat.on response of t.e BRB and t.e force redist.ibut.on wit.in t.e syst.m aft.r t.e BRBs fract.re. t.e developed finit. element.model was analyzed using increment.l dynamic analysis approach t. quant.fy t.e seismic performance of BRKBt.F. t.e result. show BRKBt.F has excellent.seismic performance wit. well cont.olled st.uct.ral responses and resist.nce against.collapse. In addit.on, life cycle repair cost.of BRKBt.F was assessed using t.e next.generat.on performance-based eart.quake engineering framework. t.e result. confirm t.at.BRKBt.F can effect.vely cont.ol t.e st.uct.ral and non-st.uct.ral component.damages and minimize t.e repair cost. of t.e st.uct.re under different.ranges of eart.quake shaking int.nsit.es. t.is st.dies conclude t.at.BRKBt.F is a viable and effect.ve seismic force resist.ng syst.m.

Cell Research 2005年第3期15卷 143-149页

Progression of cells from G2 phase of t.e cell cycle t. mit.sis is a t.ght.y regulat.d cellular process t.at.requires act.vat.on of t.e Cdc2 kinase, which det.rmines onset.of mit.sis in all eukaryot.c cells. In bot. human and fission yeast.(Schizosaccharomyces pombe) cells, t.e act.vit. of Cdc2 is regulat.d in part.by t.e phosphorylat.on st.t.s of t.rosine 15 (t.r15) on Cdc2, which is phosphorylat.d by Wee1 kinase during lat. G2 and is rapidly dephosphorylat.d by t.e Cdc25 t.rosine phosphat.se t. t.igger ent.y int. mit.sis. t.ese Cdc2 regulat.rs are t.e downst.eam t.rget. of t.o well- charact.rized G2/M checkpoint.pat.ways which prevent.cells from ent.ring mit.sis when cellular DNA is damaged or when DNA replicat.on is inhibit.d. Increasing evidence suggest. t.at.Cdc2 is also commonly t.rget.d by viral prot.ins, which modulat. host.cell cycle machinery t. benefit.viral survival or replicat.on. In t.is review, we describe t.e effect.of viral prot.in R (Vpr) encoded by human immunodeficiency virus t.pe 1 (HIV-1) on cell cycle G2/M regulat.on. Based on our current.knowledge about.t.is viral effect. we hypot.esize t.at.Vpr induces cell cycle G2 arrest.t.rough a mechanism t.at.is t. some ext.nt.different.from t.e classic G2/M checkpoint.. One t.e unique feat.res dist.nguishing Vpr-induced G2 arrest.from t.e classic checkpoint. is t.e role of phosphat.se 2A (PP2A) in Vpr-induced G2 arrest. Int.rest.ngly, PP2A is t.rget.d by a number of ot.er viral prot.ins including SV40 small t.ant.gen, polyomavirus t.ant.gen, Ht.V t.x and adenovirus E4orf4. t.us an in-dept. underst.nding of t.e molecular mechanisms underlying Vpr-induced G2 arrest.will provide addit.onal insight. int. t.e basic biology of cell cycle G2/M regulat.on and int. t.e biological significance of t.is effect.during host.pat.ogen int.ract.ons.
