Öğe A comparative study on the dynamic analysis of multi-bay stiffened coupled shear walls with semi-rigid connections(Springer, 2007) Aksogan, O.; Choo, B. S.; Bikce, M.; Emsen, E.; Resatoglu, R.The present work considers dynamic analysis of multi-bay shear walls having any number of stiffening beams resting on rigid foundations.Öğe Non-planar coupled shear walls with stiffening beams(Academic Journals, 2009) Emsen, E.; Turkozer, C. D.; Aksogan, O.; Resatoglu, R.; Bikce, M.This paper concerns itself with the static analysis of non-planar coupled shear walls with any number of stiffening beams. Furthermore, the change of the heights of the stories and connecting beams from region to region along the height are taken into consideration. The stiffening of coupled shear walls is realized by placing high connecting beams at the levels of whole or partial stories used as storage or service areas. The analysis is based on Vlasov's theory of thin-walled beams and Continuous Connection Method (CCM). In the analysis, the compatibility equation has been written at the midpoints of the connecting and stiffening beams. The method of analysis presented was compared with the SAP2000 structural analysis program. The results obtained showed good agreement, verifying the accuracy of the proposed method, which can efficiently be used for the pre-design computations of tall buildings.Öğe A simplified dynamic analysis of multi-bay stiffened coupled shear walls(Elsevier Sci Ltd, 2007) Aksogan, O.; Bikce, M.; Emsen, E.; Arslan, H. M.The forced vibration analysis of a multi-bay coupled shear wall on an elastic foundation has been studied. The analysis considers shear walls with a finite number of stiffening beams, the properties of which vary from span to span and/or from section to section in the vertical direction. The continuous connection method is employed to find the structure stiffness matrix. The structure mass matrix is found with the lumped mass assumption. A time-history analysis has been carried out using the Newmark numerical integration method. A computer program has been prepared in the MATHEMATICA computer algebra system and a problem has been solved for verification and comparison purposes. The results obtained by the present method have been compared with those obtained using the SAP2000 structural analysis program and a good match has been observed. The two advantages of the proposed method are the simplicity of its data and the extremely short computation time, which render it an effective method for the predesign of high-rise buildings.

Pierced shear walls weakened by doors, windows and corridors, necessitate particular attention, since they are highly indeterminate. In this study, the static analysis of non-planar pierced shear walls with yielded connections modelled as equivalent rotational springs is considered. To carry out a quick predesign of non-planar pierced shear walls, an elegant technique called Continuous Connection Technique (CCT) has been used in conjunction with Vlasov's theory of thin-walled beams. The governing differential equations, in the CCT, are the compatibility equations written for the vertical displacements at the midpoints of the connecting beams. There is a contribution pertaining to the semirigid beam-wall connections in these equations. The connecting beams are assumed to have the same properties and spacing along the entire height of the wall and all rotational springs have equal constants.
