Summary: The basic difference in behaviour of large-panel structures when compared with traditional monolithic structures with shear walls lies in the bahaviour od joints. The joints have an ability to absorb and dissipate the energy applied. Such structure behaves as if smaller seismic load was applied to it. At such structure, damage are generally much smaller and repair work is simpler since it almost always concern vertical joints. Some regulations (including our current code) treat the large-panel structures as if they were monolitic when determining design seismic load, while some other regulations stipulate that the design load must be two times higher that it is in the case of monolitic structures. The proposed research work, both theoretical and experimental, should prove exactly the opposite. Design loads should be smaller, large-panel structures will have satisfactory bearing capacity and stability, and, from the economical aspect, they will become more interesting for investors. Their application in building construction will thus be treated more adequately.

Keywords: large panel structure, earthquake, nonlinear dynamic analysis, parametric study, DRAIN-2D-2, elastic panel, nonelastic joints,

Research goals: This research project should contribute to the modification of the basic approach to large-panel structures. The large-panel structure must be designed that it behaves as flexible structure but with controlled deformations. Joints, particularly vertical ones, should constitute the area of absorption and dissipation of energy applied to the structure during the earthquake. Specific aims of the research: 1. Improve knowledge about differences in behaviour of large-panel and shear wall monolithic structures 2. Improve knowledge about correlation between joint and whole structure ductility 3. Improve knowledge about correlation between applied and absorbed energy 4. Improve aseismic design codes. Give suggestion for decrement the actual design seismic load for large-panel structures 5. Install DRAIN-2D-2 program and incorporate new mathematical models for large panel structures design 6. Chose mathematical models which simulate the experimental results obtained in this project and other similar projects
