Nonlinear Earthquake Response Analysis Of Five-Layer Rapid Wall Structure And Experiment Study

At present, with the deepening development of the energy conservation and emission reduction and the rapid development of new green building materials, as a new kind of building material, rapid fiber gypsum wall board material has been used more and more in the building structure. Structure Laboratory of Shandong Jianzhu University has established five fiber gypsum wallboard crash full-scale models to study. The following areas has been studied,rapid load-bearing wall panels method of calculating capacity, rapid load-bearing walls wall of the internal force, rapid load-bearing walls wall plate structure of seismic performance under horizontal load and so on. However, all of those are limited to destroy the wall structure of the overall nonlinear static analysis, and the structure of nonlinear dynamic analysis has not been further discussed.Time history analysis is one of basic methods of the nonlinear seismic analysis of the basic methods. Because it can effectively simulate due to its entire process of flexible, cracking and damage, and it can also discover the weak links of structure, in the seismic analysis it will receive more and more attention and application.Especially in the reinforced concrete structure, steel structure has shown significant value and much research has been taken. However, dynamic analysis is relatively few in the seismic performance of masonry Structures.Therefore, this article apply dynamic analysis to study the nonlinear seismic response analysis of the rapid wall structure.The results of the study will further promote the rapid wall system and it has important theoretical and practical significance.The article was based on the project's five-story rapid wall masonry solid model by finite element software ANSYS APDL language in the native programming, building a finite element model, further study the earthquake response of the kind of wall structure under design earthquake and rare earthquake. This article includes the following:(1) Discussing the development of new Rapid Wall materials and research status, Introducing the theoretical basis of this trial and technical regulations. Based on the original test data select suitable for rapid wall structure under earthquake nonlinear analysis component restoring force model-"bilinear restoring force model".(2) Under the second-class venues type condition, enter three different seismic waves to the rapid wall structure and adjust the input acceleration amplitude to study the nonlinear dynamic analysis of the structural under the earthquake. Main research earthquake response and earthquake response characteristics of the situation under the six degrees of earthquake intensity. The seven minimum security earthquakes and seven degrees strong earthquake, including the structure of the top floor displacement time history, the maximum story drift_and maximum seismic shear layer.(3) By time history analysis method, it shows that in elastic and plastic state, rapid wall board structure meet the three levels earthquake-proof requirements, which is that "under the minor earthquake, the structure is not bad, and under the medium earthquake, the structure can be repaired, and under the strong earthquake, the structure will not be pulled down". And also we can come the conclusion that rapid wall can be used as load-bearing walls.
