Comparative study of behaviour of reinforced concrete beam-column joints with reference to monolithic and non-monolithic connection

Abstract

The implementation method of reinforced concrete construction has progressed very rapidly. This development aims to speed up time and reduce costs. One of the most widely used methods is the precast method, but the less popular precast method is used for simple storey buildings. Therefore, in this study the semi-precast method, which is easy to implement in a simple storey building, was presented. Parts of columns and beams were cast in place with different casting times. Therefore, the connection become non-monolithic. This study presented a comparison between the deflection and the static load capacity that can be received by the connection of reinforced concrete beam-column which is monolithically connected and non- monolithic. 3 sets of specimens were made to represent monolithic and non-monolithic specimens. The nonmonolithic specimens were made with 2 models, i.e. without and with a notch. The beam-column connections were tested experimentally and compared to the monolithic beam-column connection. The results showed that the notch on non-monolithic test specimens can increase the load capacity and reduce deflection compared to the specimen test without notch. The experimental results also showed that the strength and performance of structural non-monolithic beam-column connections were as good as those of monolithic beam-column joints.

Seismic Behavior of RCS Composite Frame Structure with Rigidity Zone Factor Variations of Beam-Column Connections

“…Pada semua sistem struktur rangka seperti juga struktur rangka komposit RCS, perilaku pertemuan balok-kolom berperan cukup penting dalam mendistribusikan gaya antar elemen-elemen struktur yang bertemu pada lokasi tersebut. Pertemuan balok-kolom yang tidak cukup kuat dapat menyebabkan terjadinya keruntuhan elemen struktur yang bertemu pada daerah tersebut (Yuliati et al, 2018). Sejumlah pengujian experimental dan analisis numerik telah dilakukan untuk mengetahui perilaku pertemuan balok-kolom sistem rangka pemikul momen RCS.…”
