Shear wall of multi story wall beam system for tall buildings

Abstract

Precast construction with wall beam system has gain many advantages in multi storey building construction. In addition, high rise building plays an important role not only in accommodation issue but also in safety issue of the lives during construction and living in that building. Therefore, most of the engineers explore the safer construction methods and economical solution for the construction of multi storeyed building. Moreover, wall beam system has a high resistance in the earthquake (lateral) load since the shear wall has been used as one of the main structural elements. Many research and testing has been done in shear wall analysis using various methods to determine the strength, the behaviour and failure mechanism of the shear wall. In this research work the dynamic properties and failure mechanism of scale-down shear wall with regular openings subjected to real seismic loads on shake table test are discussed. For this purpose, the experimental works are carried out in accordance with PGA (peak ground acceleration), natural frequency, mode of shapes, pushover testing and failure mechanism of the shear wall are evaluated and compared with the results from FEM software (ETABS). To sum up, wall beam system has many advantages in construction and it can be said that it is the most time effective construction method among the other construction methods especially if IBS is introduced. In addition, this type of structural system can withstand the lateral loads (earthquake) than any other types of the structure. Therefore, nowadays, this method has been accepted as one of the most appropriate methods in tall building construction system.
