Abstract

Connections of structural members are very important elements in the design and construction of seismic-resistant buildings. The quality of the connection governs the failure or collapse of a building. Idealization of the design and behavior of Beam Connections (BC) in precast buildings is very crucial in providing a sound and ductile structure. Precast concrete system has several advantages for its construction quality particularly in terms of material due to its manufacturing process with better quality assurance and control in the making process. Other advantages are faster installation, and more practical in construction process. One of the structural members in a building structure is a beam. The beam is mainly intended to resist the internal bending moments which may cause tension failure and the internal shear forces that can lead to abrupt brittle failure. Hence, this study concentrated on the behavior of beam’s precast connection in seismic-resistant houses. The connection was a dry connection. The advantages of using dry connection are very quick and simple in installation without any casting during construction process. The dry connection system uses bolted steel rods to connect between beam members and beam stubs. Specimen BK 1 (single-story house) produced good ductility. From the experimental testing, this specimen has provided full ductility. On the other hand, Specimen BK 2 (two-story house) produced limited ductility and specimen can be considered to have limited ductility. Keywords: beam, cyclic loading, dry connections, precast concrete, seismic-resistant houses.
