Abstract: The method uses the substructure transformation inherent in the Choleski decomposition and involves a partial release of the interior coordinates. A comparison is made between the decomposition method and the standard one which requires the full release of all interior degrees-of-freedom before the boundary problem is solved. It is concluded that the decomposition method requires less numerical calculations and manipulates less data than the standard method. In addition, the numerical calculations for the substructure decomposition method can be performed within the context of the Choleski decomposition method and requires few new computer routines.

Cladding‐Frame Interaction
Robert M. Henry,Frederic Roll +1 more
TL;DR: In this paper, the interaction between a precast wall cladding panel and a reinforced concrete frame under linear static and dynamics forces has been performed and two computer programs were written to evaluate the effects on the lateral displacements and dynamic characteristics of a moment resisting frame when the cladding is incorporated into the analysis as a structural component.
