| It is the more outstanding of the city to prevent disaster along with large quantity that modern city population come together with economy high prosper, "nations reduce disaster in the decade" is opened especially since the 90's activity, it is each to prosper the nation to value all and very. Shake right on the spot the earthquake harm the precept to see, nearly 30 remaining years of lifes are from Tang of San Fernando earthquake, China Tangshan earthquake in 1976, United States Loma Prieta earthquake in 1989, United States Northridge earthquake in 1994, and Japan Kobe earthquake in 1995, people discovers to have done the large building that anti-earthquake design to tumble down with bridge still or damage seriously, as a result in recent years, the relevant scholar in all countries faces the earthquake harms the precept with enlighten, many new researches and discussion are spread about anti-earthquake material and component. Large quantity theories research enunciation: It is former to regard guaranteeing the strength of the framework construction as the building anti-earthquake of the point designs when the strong earthquake takes place, is a circumstance that strength resist only, did not give the building to transform the ability sufficiently bottom, the earthquake disaster loses usually very big. Therefore, It is pop topic to building material and component that can absorb earthquake. These works are given below:energy research for becoming anti-earthquake realm heats of the earthquake energy order. In this paper, it was put forward about Fe/Zn aseismatic composite thought, for validating aseismatic capability and dissipating energy of Fe/Zn aseismatic composite, author bring forward to do numerical value test about material capability with international current finite element software ANSYS. To Fe/Zn composite, it was adopted to evanescence time-course analysis, and calculated stress-strain curve of Fe/Zn composite under earthquake wave load, for the composite, Zn entered mold phase and formed resort ring, this proved Fe/Zn composite possessed effect of aseismatic capability and dissipating energy, and Fe was on elastic ground in order to ensure structure not occur destroy,and it offer adequate resume force.liquid press the machine of damp in earthquake respond of applied foreground Combining the combinative engineering practiced the outlook the. Five main progresses have made in this paper:(1) It is put forward proposition of developing Fe/Zn anti-earthquake composite first. For composite, Fe is contributing to ensure component rigidity, resilience and not occur big distortion; Plastic distortion of Zn can alter composite vibration cycle, and absorb earthquake energy. (2) Three-dimensional finite element analysis of antiseismic capability of Fe/Zn composite. It is provided to the theories for the system of the new material according to.(3) It is the very first time to study responds process of earthquake of metal layer composite. Observed in "Time Hist Postpro" that biggest stress of Fe is lower than the yield intensity of Fe, the biggest stress of Zn is bigger than the yield intensity, Fe supports load and Zn absorbs energy are proved.(4) It is studied to microcosmic mechanism of Fe/Zn composite plastic consume energy, that macroscopical antiseismic capability of Fe/Zn composite is response of microcosmic mechanism of Fe/Zn composite plastic consume energy is further proved. (5) Put forward to press with the liquid for the very first time the machine of damp replace just the knot block to let up bridge is in earthquake respond of breakage degree.In summary, this thesis realizes to use for the very first time the metal plastic consumes energy or component displacement moves the variety consumes energy realize the hold out earthquake break to avoid personnel's dead and injured conceives, regarding the effect of Baushinger and the theories of plastic as basises, calculation and discuss the Fe/Zn under the earthquake a function Stress-Strain to changes curve,for... |
