為了彌補這方面的研究不足，本文對兩種連接方式足尺復合墻片進行了低周反復荷載作用下的恢復力試驗，以了解配筋砌塊復合墻的平面外抗震性能，同時研究平面外變形對墻體平面內抗震性能的影響，為配筋砌塊復合墻的設計提供依據。Not only the load is considered, but also the distance, the span, the wide and the percent of the reinforcement is considered. the chosen section is also meeted the stiffness
該公式不僅考慮到荷載大小、而且考慮了梁格的間距、跨度、梁寬、以及梁的配筋率等因素，且所選截面滿足剛度要求。The scc has the following advantages : remarkably reducing the noisy pollution and the worker s labor intensity in construction, deducing the rough surface or segregation because of missing - vibration or excessive - vibration in conventional construction, resolving the quality - defect problems resulting from lacking - vibration in the section of complex shapes and densely - packed reinforcement area. at the same time, large of industrial solid waste such as fly ash and blast furnace slag is utilized in the proportioning of scc. it is helpful in comprehensive utilization of resource and environment protection, so the scc belongs to " green concrete ", it is a branch of hpc which will be developed in the future
這種混凝土可以顯著降低混凝土施工中的噪音污染；大幅度減輕工人的勞動強度；減少傳統混凝土施工中因漏振或過振造成的麻面或離析；解決了配筋密集、結構復雜部位因振搗不足而造成的質量缺陷問題；同時，由於自密實混凝土在配製中，大量利用粉煤灰、高爐礦渣等工業固體廢棄物，有利於資源的綜合利用和生態環境的保護；從而被譽為「綠色混凝土」 ，是未來混凝土向高性能發展的方向之一。Firstly, the master zhang binbin ' s tests further verified that the design methods brought forward by the code for design of reinforced concrete high - rise structure ( jgj3 - 2002 ) can not satisfy basic seismic requirement. at the same time, our research group find that some acceptable improved reinforcement arrangement scheme in domestic and foreign researches can not attain satisfying ductility performance
其中首先通過碩士研究生張彬彬的試驗研究工作，進一步證實《高層建築混凝土結構技術規程》 （ jgj3 - 2002 ）提出的設計方法不能滿足抗震基本要求；同時查明，國內外已提出的某些施工可以接受的改進配筋方案仍未達到較滿意的延性性能。In order to reveal load mechanism and failure mode of thick pile caps, by means of the test of 1 / 4 - scale models of thick pile caps with six piles and post - handling study of 3 - dimensional non - linear finite element adina, this paper points out the shortage, which is that the design of pile caps is carried out by flexural strength in chinese technical code for building pile foundations jgj94 - 94 and american reinforcement concrete building construction code aci318 - 02, promulgates that the failure mode of thick pile caps is punching failure and load transfer mechanism is the strut - and - tie, which is that zones of concrete with primarily unidirectional compressive stresses are modeled by compress struts, while tension ties are used to model longitudinal reinforcement over pile
摘要為揭示厚承臺的傳力機理和破壞形式，通過對4個1 : 5比例的六樁厚承臺的模型試驗研究與三維非線性有限元adina的后處理研究，指出中國建築樁基技術規范jgj94 - 94與美國鋼筋砼房屋建築規范aci318 - 02規范中，承臺以彎曲強度進行配筋計算的設計方法之不足，揭示出厚承臺的破壞模式是沖切破壞，傳力機理是以帶有主要單向壓應力的砼區域作斜壓桿，樁頂區域的縱筋作拉桿的空間桁架。Have to out : 1 temperature constructional reinforcing not can place in heat area to mass concrete design. temperature constructional reinforcing of bottom of mass concrete need content that owing to temperature change produce bottom control stress smaller than anti - pull strength at the same. get minimum rate of reinforcing to content construct request
得出： 1在大體積混凝土結構的溫度構造鋼筋配置中，構造鋼筋不宜放置於高溫區；大體積混凝土的底部溫度構造鋼筋應滿足溫度變化產生的底部約束拉應力小於混凝土同齡期的抗拉強度的要求，從而求出抗拉要求的最小配筋率。Effect of load and indirect load such as shrinkage, creep was often taken into account separately to satisfy the requirement of crack width in reinforcement design of large area prestressed concrete frame structures
摘要大面積預應力混凝土框架結構設計時一般將直接荷載產生的作用與溫度、混凝土收縮產生的作用分開計算，分別配筋以滿足裂縫控制的要求，這種做法不盡合理。Middle strength ( 1370mpa ) spiral ribs steel wires is a new type of high strength and good ductility and anchoring strength rolled steel, which is the ideal steel for the high effective pre - stressed reinforced concrete hollow slab. the slab with it has lower price than the traditional ones as well better mechanical property
中強（ dw1370 ）螺旋肋鋼絲是一種強度高、延性好、錨固性能優良的新型材料，是高效預應力空心板的理想的受力鋼筋，以這種鋼筋為配筋的預應力空心板不僅具有較好的力學性能，滿足現代建築市場對預應力空心板的要求，而且其價格比低於傳統的冷加工鋼筋。In the light of the deficiency of the routine calculating method in the application of multi - curve style prestress steel bar in the large span structures, an applied program is written to calculate the loss of the prestress. fem is used to calculating the concrete stress of the frame beam under prestress load, in the process of which, many successful improvements have been made in the element division, load application and the treatment of the support restraint
針對常規計算方法在大跨結構中預應力筋多波曲線配置應用中的不足，編制了計算預應力損失的應用程序；用fem計算了框架梁在預應力載荷作用下的混凝土應力，其間在單元劃分、載荷施加及支座約束處理上有成功的改進。In this paper, there are three main purposes to be attained. firstly, enough ductility of coupling beams is needed, namely no shear failure occurs too early. secondly, the capacity of energy dissipation is satisfied on the grounds of enough stiffness
本文的主要研究目的是首先保證連梁具有足夠的延性，即保證連梁端部在達到較大彎矩之前，不過早發生剪切破壞；其次是在保證剪力墻整體強度的前提下，連梁還需具有良好的耗能性能；連梁的配筋構造不太復雜，方便施工。分享友人
