Abstract
Earthquake negatively affects the behavior of reinforced concrete frame systems that have slab discontinuities. As a result of differences in diaphragm behavior according to slab void ratio and position, lateral loads cannot be distributed to vertical bearing elements in proportion to their rigidity. In this study, the topic of differences in the behavior of reinforced concrete frame system under lateral load if void ratio and position of the slab change have been examined numerically. For this purpose, five single-story three-dimensional carrier frame models with different void ratios and positions were created in the ANSYS program analyzing according to the finite element method. As a result of the study, an increase in slab void ratio of reinforced concrete frame type carrier systems resulted in displacement in more significant amounts. Along with 25% being a safe void ratio in terms of rigid diaphragm behavior when the void ratio is 50%, whether the void is symmetrical or not becomes extremely important in terms of behavior.
期刊介绍：
The Journal of Construction is aimed at professionals, constructors, academics, researchers, companies, architects, engineers, and anyone who wishes to expand and update their knowledge about construction. We therefore invite all researchers, academics, and professionals to send their contributions for assessment and possible publication in this journal. The publications are free of publication charges.
OBJECTIVES
The objectives of the Journal of Construction are:
1. To disseminate new knowledge in all areas related to construction (Building, Civil Works, Materials, Business, Education, etc.).
2. To provide professionals in the area with material for discussion to refresh and update their knowledge.
3. To disseminate new applied technologies in construction nationally and internationally.
4. To provide national and foreign academics with an internationally endorsed medium in which to share their knowledge and debate the topics raised.
