Analysis of stiffened multi-bay coupled shear walls on elastic foundation using continuous connection method

In this article, the static analysis of a multi?bay coupled shear wall, resting on an elastic foundation, having any number of stiffening beams, is studied employing the continuous connection method (CCM). The shear wall is considered to be made up of a finite number of sections in the vertical direction, with or without stiffening beams between each pair of consecutive sections. Each bay of every section of the wall has fixed connecting beam properties throughout the particular region. The method of analysis, which warrants thickness variation and elastic beam-wall connections, treats the discrete connecting beams as a continuous layered medium, the shear force per unit of length integrated starting at the top expressing the unknown functions. To implement the foregoing analysis, a computer program has been prepared in the MATHEMATICA computer algebra language system. Using this program, a number of problems from the previous literature, has been solved and the results have been compared with those obtained by SAP2000 structural analysis program and a perfect agreement has been obtained to support the validity of the present method

Non-planar coupled shear walls with stiffening beams

9th International Conference on Computational Structures Technology, CST 2008 --2 September 2008 through 5 September 2008 -- Athens --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 predesign computations of tall buildings. © Civil-Comp Press, 2008
