“…The ductility of precast beam-column joints using dowels is smaller than the ductility of monolithic beamcolumn joints due to the presence of grouting in the beam connection area which makes the cross-section stiffer due to the greater compressive strength of the concrete in that area [24][25].…”

The beam-column connection plays an important role in the building structure, especially when the load is cyclic. The main problem that must be solved is the beam and column connection panels. The purpose of this study was to analyze the characteristics of the hysteresis loop of the displacement load relationship with the control displacement of the precast beam-column connection due to cyclic loading. The research method used is the experimental method with a measurable object design test and a special testing method. The results of this study indicate that normal concrete has a compressive strength of 26.43 MPa, while grouted concrete has a compressive strength of 36.97 MPa. The findings of this study also show that the bond stress grouted concrete increases by 102.4% from normal concrete for D13 diameter screw reinforcement, while for D16 diameter, the adhesive stress increases by 51.63%. The findings of this study also show that in the ultimate condition, the load obtained in the tensile load is 13.58 kN with a displacement of 87.58 mm, while the compressive load is 12.62 kN with a displacement of 88.30 mm. This study concludes that the behavior of precast beam-column joints with dowels is stronger in resisting cyclic loads.

“…Generally, the response of continuous concrete deep beams has not investigated by the past researches especially for rubcrete mixes while it can be found some researches about an empirical equations to solve the seismic loads [18][19][20][21]. Numerical solutions by different software programs is interested with the reinforced concrete beams [22].…”

Continuous deep beams (CDBs) are the most used members in constructions with highly exposing to different types of dynamic loads. It is well known that; the concrete is a brittle material and has a weak resistance to energy absorption. Using scrapped tire rubber enhances the concrete energy absorption for sustainability purposes. Timoshenko beam theory has been used to solve CDBs subjected to sinusoidal load and has been adopted for verification of numerical results of ANSYS APDL V.15.0. Seven concrete mixes have been simulated with different types and amounts of aggregaterubber replacements. Several parameters have been studied like replacing type, percentages, shear span of beam to depth ratio (a/h) and load intensity. It was found that Timoshenko beam theory can be used for harmonic loading CDBs. Furthermore, replacement in general provided more ductility due to rubber elasticity property. Gravel replacement by 45% has the larger displacement values among the other types. Also, it has been noted that, the sensitive of concrete deep beams towards a/h ratio stills considerable for harmonic loads, i.e. minimizing the ratio leads to decrementing the deflection wave amplitudes.

“…Most of Indonesia's areas are prone to earthquakes [11]. Post-earthquake study showed that many buildings were heavily damaged, including non-engineered buildings mostly dominated by residential houses [12]. Most recent earthquake events (Palu earthquake, 2018 and Majene-Mamuju earthquake, 2021) proved the seismic vulnerability of non-engineered buildings with RC frame infilled with masonry.…”

Every year earthquakes occur in various regions in Indonesia because Indonesia is located near earthquake faults. The cyclic lateral loading test in the laboratory has been widely used to simulate lateral loads caused by earthquake events. This research is an experimental study on the behavior of prefabricated foam concrete as an infill wall against lateral cyclic loads. P refabricated foam concrete was used in this study to make it an alternative to brick and autoclaved lightweight concrete (ALC) blocks that have been widely used as infill wall s. This study analyzes the relationship between performance levels, lateral loads and drift s ratio on RC infilled prefabricated foam concrete. Lateral cyclic loading with displacement control method was applied to evaluate the structural behavior where the test refers to ASTM E2126-02a. This study adopts FEMA 273, which regulates the performance levels to be achieved b y the structure of a building. The results showed that at performance levels Operational Level (OL), Immediate Occupancy (IO) and Life Safety (LS), the RC frame infilled with prefabricated foam concrete blocks had a drift ratio of 0.2%, 1.2% and 2.4%, respectively. Damage to the RC frame infilled with prefabricated foam concrete blocks was similar to the masonry infilled RC frame.
