This study presents the formulation of beam transition elements and transition zone elements for the
effective finite element ?lalysis of the transition regions of coupled wall structures. Beam transition
element can be described as the quasi beam element which is replaced by an equivalent plane stress element,
keeping equally. the basic behavior of beam element. based on the kinematic ?ld force
constraints between beam and wall element. These beam transition elements solve the incompatibility
related to different degrees of freedom between beam and wall element in transition regions. Also. the
stiffness matrices of transition zone elements which are directly connected with beam transition
ele¦Ð¦Ånts in transition regions can be derived from the equivalent constraint conditions. These
elements provide the reasonable mesh grading schemes for transition regions and can be usefully applied
to the transition regions of all structures that the interactions of wall and beam element are considered.
