The Effect of Shear Wall Distribution on the Dynamics of Reinforced Concrete Structures

Abstract

The inclusion of a soft storey in multistory concrete buildings is a feature gaining popularity in urban areas where land is of exorbitant cost. In earthquake prone zones, this feature has been observed in post earthquake investigations. Although engineers are prepared to accept the notion that a soft storey poses a weak link in Seismic Design, yet the idea demands better understanding. The following study illustrates the importance of the judicious distribution of shear walls. The selected building is analyzed through nine numerical models which address the behavior of framed structures. The parameters discussed include, inter alias, the fundamental period of vibration, lateral displacements, axial and shear forces. It is noticed that an abrupt change in stiffness between the soft storey and the level above is responsible for increasing the strength demand on first storey columns. Extending the elevator shafts throughout the soft storey is strongly recommended.

Dongxia W., Mourad R., Mohammed EG, Rabah D., Rachid B., Bin L., Xiangping X ., Yixin S., Jun Y., Seyed MM, Iman Hajirasouliha emphasize that an innovative product can significantly reduce the cost of construction products, while ensuring an increase in the quality of construction products [5][6][7][8][9]. Modern views on the issues of hygrothermal behavior of a multilayer building envelope, the microstructure of cement paste during carbonization at atmospheric pressure and many other issues of the innovative development of construction industries are widely covered in the works of Sahil G., Sudhir M., Akunyumu, S., Fugar, FDK, Adinyira, E ., Danku, JC, Behzad K., Sherif M., Hassan K., Sonia L., Yanbin Zhang, Zhe Wang, Sheng Ding, C., Salleh, H. [10][11][12][13][14]. Scientist Anund Vogel in his scientific work conducted a study of the relationship of the motivational system for stimulating innovation in the construction sector using the example of the use of consulting contracts [15].…”
