【摘要】：木結構建筑是中國古建筑的典型代表,其歷史悠久、結構復雜多樣、抗震性能優(yōu)越,是中國古代工匠的智慧結晶,具有極高的文物價值、社會價值和科學價值。榫卯連接是中國木結構建筑的靈魂所在,同時榫卯節(jié)點的破壞也是木結構常見震害之一,所以研究榫卯連接對古建筑木結構的保護和修繕具有重要意義。本文通過有限元軟件進行模擬分析,對不同位置燕尾榫縫隙的木構架承載性能開展了分析研究。文章對榫卯連接的種類、受力機理及破壞形態(tài)進行了歸納總結。以《營造法式》作為規(guī)范,建立了八等材燕尾榫木構架模型,利用有限元軟件進行數(shù)值模擬分析,研究了燕尾榫間縫隙對八等材木構架承載性能的影響。分別以無縫、端縫、側縫和端側縫燕尾榫木構架為研究對象,在豎向配重下水平方向施加靜力往復荷載,研究了木構架的抗側移剛度及滯回耗能性能。在不同豎向配重作用下,同種縫隙燕尾榫木構架性能不同。在水平靜力往復荷載作用下,得到了木構架的滯回曲線、骨架曲線、摩擦耗能曲線和拔榫量。結果表明隨著豎向配重的增大,燕尾榫木構架的滯回曲線“捏縮”現(xiàn)象越明顯,抗側移剛度和摩擦耗能越大。在相同豎向配重作用下,不同縫隙燕尾榫木構架性能不同。木構架的性能優(yōu)劣從整體上呈現(xiàn)“無縫燕尾榫端縫燕尾榫側縫燕尾榫端側縫燕尾榫”的規(guī)律,其中側縫對木構架抗側移剛度、抗震等性能的損傷遠大于端縫。燕尾榫縫隙的存在降低了木構架的承載性能,采取木板填充縫隙的方法建立新的木構架模型。數(shù)值模擬結果表明修繕后的木構架性能遠大于帶縫隙模型,并且與無縫模型接近。建立了柱根糟朽木構架模型,通過糟朽模型與完好模型的對比,分析柱根糟朽對木構架承載性能的影響。
[Abstract]:Wood structure architecture is a typical representative of ancient Chinese architecture. It has a long history, complex structure, excellent seismic performance, is the wisdom of ancient Chinese artisans, and has a high value of cultural relics. Social value and scientific value. Tenon joint is the soul of Chinese wood structure, and the destruction of joint is one of the common earthquake damage of wood structure. Therefore, it is of great significance to study the tenon and joint connection for the protection and repair of the ancient building wood structure. In this paper, the finite element software is used to simulate and analyze, This paper analyzes and studies the load-bearing performance of wood frame with dovetail tenon in different positions. This paper summarizes the types, mechanical mechanism and failure form of tenon and joint. In this paper, the model of Eight-grade wood frame with tenon and tenon is established, and the influence of the gap between tenon and tenon on the load-bearing performance of the truss is studied by using the finite element software. In this paper, the lateral joint and the end-side joint with dovetail tenon wooden frame are studied. Under the vertical counterweight, static reciprocating load is applied in the horizontal direction, and the lateral stiffness and hysteretic energy dissipation performance of the wood frame are studied. Under different vertical counterweights, the lateral stiffness and hysteretic energy dissipation of the wood frame are studied. Under horizontal static reciprocating load, hysteretic curve, skeleton curve, friction energy dissipation curve and tenon quantity of wood frame are obtained. The results show that the hysteretic curve, the skeleton curve, and the tongue-drawing quantity of the same type of slotted tenon and tenon frame are obtained under horizontal static reciprocating load. The results show that with the increase of vertical counterweight, The more obvious the "pinch" phenomenon of hysteretic curve of dovetail tenon wood frame is, the greater the anti-lateral stiffness and friction energy are. Under the same vertical counterweight, The performance of wood frame is different from that of slotted dovetail tenon. The performance of wood frame presents the rule of "seamless dovetail end joint and side joint dovetail tenon", in which the lateral joint is resistant to lateral displacement stiffness of wood frame. The damage of seismic and other properties is much greater than that of end seam. The existence of dovetail joint reduces the bearing capacity of wood frame. A new wood frame model was established by using plank filling method. The results of numerical simulation show that the performance of the repaired wood frame is much larger than that of the seamless model, and is close to the seamless model. Through the comparison between the rotten model and the intact model, the influence of post root rot on the bearing capacity of wood frame was analyzed.
