box system that consists of reinforced concrete walls and slabs is
adopted for many high-rise apartment buildings recently constructed. In
an apartment building, shear walls may have one or more openings for
functional reasons. Some researches on the analysis of shear wall with
openings were performed, but some restrictions prevent those research
results from being applied to the practical analysis and design
procedure. It is necessary to use fine mesh finite element models for an
accurate analysis of a box system structure with openings. But it would
take a significant amount of computational time and memory if the
entire building structure were subdivided into a finer mesh. An
efficient analysis method that can be used regardless of the number,
size and location of openings is proposed in this study. The analysis
method uses super elements developed using the matrix condensation
technique. Static and dynamic analyses of example structures having
various types of openings were performed to verify the efficiency and
accuracy of the proposed method. The analyses of example structures
demonstrated that the proposed method can be used for the analysis of a
shear wall structure with openings. Outstanding accuracy in analysis
could be achieved with drastically reduced computational time and
