     an enhanced reduced model is proposed for elastic earthquake response analysis of a class of mono-symmetric shear building structures with constant eccentricity. the proposed reduction method consists of two parts. the first stage is the construction of a reduced structural model with the degrees of freedom at representative floor levels only. in this stage, an inverse eigenmode-problem formulation is used to guarantee the limited equivalence between the original model and the reduced model. the reduced model is constructed so as to have the same fundamental natural frequency and the same lowest-mode component ratios at the representative floor levels as those of the original model. the second stage is the transformation of earthquake input forces into a set of reduced input forces. this transformation utilizes the static equivalence of lateral-torsional stiffness between these two models and is introduced to enhance the accuracy level of the reduced model. several examples of a three-dimensional mono-symmetric ten-story shear building model with constant eccentricity are presented to demonstrate the validity and accuracy of the proposed reduction method for earthquake response analysis.
