("《高层建筑结构与抗震》辅导文章五剪力墙结构内力与位移计算学习目标1、了解剪力墙结构的分类,以及各种剪力墙的受力特点;2、熟悉剪力墙的分类判别式。3、掌握整体墙和小开口整体墙的内力及位移计算、掌握双肢墙的内力及位移计算。学习重点1、剪力墙的分类及分类判别式;2、整体和小开口整体墙的内力及位移计算;3、双肢墙的内力及位移计算。剪力墙主要承受两类荷载:一类是楼板传来的竖向荷载,在地震区还应包括竖向地震作用的影响;另一类是水平荷载,包括水平风荷载和水平地震作用。剪力墙的内力分析包括竖向荷载作用下的内力分析和水平荷载作用下的内力分析。在竖向荷载作用下,各片剪力墙所受的内力比较简单,可按照材料力学原理进行。在水平荷载作用下剪力墙的内力和位移计算都比较复杂,因此本章着重讨论剪力墙在水平荷载作用下的内力及位移计算。一、基本假定剪力墙结构是一个比较复杂的空间结构,为了简化,剪力墙在水平荷载作用下计算时,作如下假定:(1)楼板在其自身平面内的刚度极大,可视其为刚度无限大的刚性楼盖;(2)剪力墙在其自身平面内的刚度很大,而在其平面外的刚度又极小,可忽略不计。因此可以把空间结构化作平面结构处理,即剪力墙只承受在其自身平面内的水平荷载。基于以上两个假定,剪力墙结构在水平荷载作用下可按各片剪力墙的等效抗弯刚度分配水平力给各片剪力墙,然后分别进行内力和位移计算。例如图6-1(a)所示的剪力墙结构可分别按图6-1(b)和图6-1(c)的剪力墙考虑。同时,现行国家标准《高层建筑混凝土结构技术规程》(JGJ3-2002)为考虑纵、横墙的共同工作,将纵墙的一部分作为横墙的有效翼缘,横墙的一部分也可以作为纵墙的有效翼缘。剪力墙的等效抗弯刚度是一个非常重要的概念,是指按剪力墙顶点侧移相等的原则,考虑弯曲变形和剪切变形后,折算成一个竖向悬臂受弯构件的抗弯刚度。图6-1剪力墙结构计算图二、剪力墙的分类为满足使用要求,剪力墙常开有门窗洞口。理论分析和试验研究表明,剪力墙的受力特性与变形状态主要取决于剪力墙上的开洞情况。洞口是否存在,洞口的大小、形状及位置的不同都将影响剪力墙的受力性能。剪力墙按受力特性的不同主要可分为整体剪力墙、本专业培养掌握生物技术及其产业化的科学原理、工艺技术过程和工程设计等基础理论、基本技能,能在生物工程和生物技术领域从事设计、生产、管理和新技术研究、新产品开发的工程技术人才。IsignedwiththeBankoftheqiluBankloancontract(contract)conventions,andIusescheme,Iwouldrequesttheloans(inwords)untilIopenedpersonalsettlementaccountwithyourBank(account),usesloanfor。Loanoperation,businessunitname:accountnumber:loanfundsfromthesepersonalsettlementaccountintotheaccountofapayment.Loansinaccordancewiththefollowingpaymentmethodstopay.One,lendertrusteepayment.DelegateqiluBankloanfundsoftheborrowertomeetthestipulationofthecontractthefollowingborrowers,counterparties,commitmentfunds,regulatorycompliance,legal,andwillingtotakethepaydisputes,lossandotherconsequencesofthedelegate.PayeeaccountnumberBanknameamountpurposeII,borrowersownpaymentmethods.QiluBankaccordingtotheborrower'swithdrawalrequesttoloanfundsdisburseddirectlytotheborrower'saccount,andindependentlybytheborrowerpaymentstoborrowerswhomeetthestipulationofthecontracttransactions.Iguaranteetoyourbankcontractsandotherproveofmaterialsubmittedbyrealandeffective.Wheninaccordancewithonepayment,Iagreewiththeaboveaccountwithyourbankloanfundsthatarenotusedforstoppaymentmanagement,stoppaidconfirmedbookrecordstablesingle13:liftedcheckpaynoticerecordstablesingle14:personalloanaheadofrepaymentapplicationacceptedtableRecordstablesingle15:loanlinesopened/cancellationapplicationapprovaltablerecordstablesingle16:qilucardawardletterselfloanlinescancellationapplicationapprovaltablerecordstablesingle17:loanlinescancellationapplicationapprovaltablerecordstablesingle18:qiluBankloanurgedreceivednoticerecordstablesingle19:arrived(quality)betrealrightprovedoutlibrarylistingrecordstablesingle20:housingmortgagerightcancellationprovedrecordstablesingle21:personalpledgeloanrepaymentcommitmentletter11.scheduleSpontaneousdateofpromulgationofthispractice,thisprocedureisissuedpriortotheimplementationoftherelevantprovisionsareinconsistentwiththisregulation,issubjecttothisregulation.TheriskmanagementDepartmentisresponsiblefortheinterpretationandamendmentofproceduresbytheheadoffice.Breakthroughtherestrictionsimposedbythispractice,shouldsubmitfileexplanationsauthoritiesfileexplanationdeemednecessaryandsubmittedtotheHeadOfficeoftheloanReviewCommitteeforapproval.Recordform1:personalloancustomerconversationtranscripttomegiventheloanapplicantbankpersonalloanapplications,accordingtoqiluBankpersonalloaninterviewsregulationsandinterviewsonthefollowingissueswiththeborrowerandtheguarantor,pleaserespond,andensurecontentauthenticity.1,yourpersonalloanapplicationmaterialsmustbesubmittedtotheqiluBankistrue,otherwiseyoushouldbearthecorrespondinglegalresponsibility.Inthisregard,doyouunderstand?Yes()No()2,youapplyforpersonalloansamountingtomillionofperiodofmonths,youdecidetotaketherepaymentoptionsare:dueaone-offdebt(),monthlyinterest,to...QiluBank:小开口整体剪力墙、双肢墙(多肢墙)和壁式框架等几种类型。1.整体剪力墙无洞口的剪力墙或剪力墙上开有一定数量的洞口,但洞口的面积不超过墙体面积的15%,且洞口至墙边的净距及洞口之间的净距大于洞孔长边尺寸时,可以忽略洞口对墙体的影响,这种墙体称为整体剪力墙。2.小开口整体剪力墙当剪力墙上所开洞口面积稍大且超过墙体面积的15%时,在水平荷载作用下,这类剪力墙截面上的正应力分布略偏离了直线分布的规律,变成了相当于在整体墙弯曲时的直线分布应力之上叠加了墙肢局部弯曲应力,当墙肢中的局部弯矩不超过墙体整体弯矩的15%时,其截面变形仍接近于整体截面剪力墙,这种剪力墙称之为小开口整体剪力墙。3.联肢剪力墙当剪力墙沿竖向开有一列或多列较大的洞口时,由于洞口较大,剪力墙截面的整体性已被破坏,剪力墙的截面变形已不再符合平截面假设。这时剪力墙成为由一系列连梁约束的墙肢所组成的联肢墙。开有一列洞口的联肢墙称为双肢墙,当开有多列洞口时称之为多肢墙。4.壁式框架当剪力墙的洞口尺寸较大,墙肢宽度较小,连梁的线刚度接近于墙肢的线刚度时,剪力墙的受力性能已接近于框架,这种剪力墙称为壁式框架。图6-2为剪力墙墙体上洞口大小对剪力墙工作性能的影响图6-2剪力墙的分类不同类型的剪力墙,其相应的受力特点、计算简图和计算方法也不相同,计算其内力和位移时则需采用相应的计算方法。以下分别介绍几种常见剪力墙的内力与位移计算方法。三、整体剪力墙的内力与位移计算对于整体剪力墙,在水平荷载作用下,根据其变形特征,可视为一整体的悬臂弯曲杆件,用材料力学中悬臂梁的内力和变形的基本公式进行计算。1.内力计算按上端自由,下端固定的悬臂梁计算其任意截面的弯矩和剪力。2.位移计算在位移计算时,由于剪力墙的截面高度较大,应考虑其剪切变形影响。当开洞时,应考虑洞口对位移增大的影响。整体剪力墙的顶点位移可按以下公式计算:(1)均布荷载作用时,如图6-3(a)所示,(6-1)本专业培养掌握生物技术及其产业化的科学原理、工艺技术过程和工程设计等基础理论、基本技能,能在生物工程和生物技术领域从事设计、生产、管理和新技术研究、新产品开发的工程技术人才。IsignedwiththeBankoftheqiluBankloancontract(contract)conventions,andIusescheme,Iwouldrequesttheloans(inwords)untilIopenedpersonalsettlementaccountwithyourBank(account),usesloanfor。Loanoperation,businessunitname:accountnumber:loanfundsfromthesepersonalsettlementaccountintotheaccountofapayment.Loansinaccordancewiththefollowingpaymentmethodstopay.One,lendertrusteepayment.DelegateqiluBankloanfundsof
