5. Conclusions
- 1
- The one-block-wide structural elements experience sudden failure, unlike two-block-wide structural elements.
- 2
- The maximum stress of the two-block-wide structural elements, i.e., the solid wall and wall with an opening, were higher than those of the one-block-wide structural elements by 30% and 50%, respectively. However, in the case of columns, this phenomenon was not repeated.
- 3
- The energy absorption quantities of two-block-wide structural elements, i.e., the column, solid wall, and wall with an opening, were higher as compared to one-block-wide structural elements by 74%, 35%, and 84%, respectively.
- 4
- Due to the slenderness effect, the peak load-carrying capacities of two-block-wide structural elements i.e., the column, solid wall, and wall with a door opening, were higher than the peak load-carrying capacities of one-block-wide structural elements by 53%, 6%, and 70%, respectively.
- 5
- The peak load-carrying capacities of the one and two-block-wide solid walls were higher than the peak load-carrying capacities of the one and two-block-wide walls with openings by 73% and 68%, respectively.
