This is a technical report for the development of slab including L-shaped void, which is compensating the faults by not only 1 way void slab but also 2 way one. In this study, we report the primary rigidity, yielding rigidity, and the shape of crack in this loading condition. This construction has two characteristics. One is mitigating the degree of anisotropy by using the slab with L-shaped void tube. Two is simplifying the design for slabs by regularly arranging the unit of tube.
