中文摘要 | 本文旨在針對規則形狀之高層構架或牆-構架結構作簡化分析方法之探 討;高層構架結構固其梁柱結點多,自由度亦高,故其結構分析程序相當繁複;因 此如何能化繁為簡,減少分析所需之計算機使用空間及提高工作效率,乃成相協 研究之重點,本文研析之方法為利用連體力學原理,將構架結構之性質化成材料 性質等效之平版,即以其相對應之等效平版代替構架:文中討論與上述相關之彈 性模數等量式及剪力模數等量式之推導,再用B樣條有限條元法對平面構架及 剪力核進行分析,例題顯示本文所提方法之簡單性、有效性及精確性;本方法也 可用於分析剪力核一構架結構。 |
英文摘要 | A simple model for the analysis of regular shape tall frame or wall-frame structures was presentedin this study. The analysis of tall building structures which have a large number of members and joints,and high degrees of freedom would involve a considerable amount of time and effort. For the sake ofsimplification, a simple plate with equivalent material properties was substituted for replacing a complexand highly redundant frame system. Methods for the derivation of the equivalent elastic modulus andshear modulus were reviewed and discussed in this paper. The tall frame or wall-frame structures werethen modelled as an equivalent thin-walled structures and were analyzed employing the B-spline Finitestrip method. The accuracy, efficiency, and simplicity of the proposed method were demonstrated bynumerical examples. This method was also suitable for analysing the shear core- frame structures. |
