A study on Structural Systems of Tall Building Using Combined RC core Walls and RC shear wall

This paper was studied performance of reinforced concrete core-wall and of com-bined core-wall and shear-wall with P-Delta effect. Model of four building of core-wall with and without shear-wall, with shear-wall 4 middle both side symmetry, with shear-wall 4 conner no symmetry and with shear-wall 4 conner symmetry. The building a long wind load located in Phnom Penh, Cambodia. To carry out the modelling and analysis for building ESI Etabs 21 software is used. Analysis from allowable condition that provide the stability of building and compared the performance of models. The result of models that using combined RC core-wall and RC shear-wall that located of shear-wall 4 conner symmetry of the building is more effective for reducing displacement and drift than other building. For the comparison of the behavior of lateral displacement, drift and P-delta effect of the building are obtained in terms minimum displacement and drift and the building more stability.
