Abstract

Research of perform of embedded precast beam was result many data (a) average tensile strength of joint between plate embedeed with plate joint was 628,55 Mpa (b)average tensile strength of joint between plate with reinforce bar D12,59 was 597,16 Mpa for tensile strength of plate with failure at reinforce bar (c) average tensile strength of reinforce bar D12,59 was 605,23 Mpa and yield strength was 425,87 Mpa (d)average tensile strength of plate 4,58 mm thick was 456,86 Mpa and  yield strength was 335,02 Mpa. For welded joint need several control quality so that no hole in that perform of welded couse can decrease tensile strength of joint. Conclusion of this research is embedded for precast concrete type wet and dry can be used for construction of joints of beam.

Abstract

Research precast beam type L shape has produced strength of flexure where it was jointed at middle of span with L shape. Problem was about strength and deflection with joint of Type L shape. Aim of this research was determined strength of flexure such deflection and maximal load would be apllicated. Precast beam type L shape consist of two beam P1 and P2 were tested at two point load was applicated. This research have produced of data of precast beam P1 and P2. Precast beam P1 has deflection 28,44 mm at maximum load 11,21 Ton. Precast beam P2 has deflection 26,71 at maximum load 11,76 Ton. Except that data, has produced also chart of load versus deflection where precast beam type L shape has behavior less for ductility approximately du/dy 1,17, where deformation inelasticity was not seem. That occur because overlapping at joint of precast concrete at middle of span.

Abstract

One alternative to replacing traditional red brick is lightweight brick, which is commonly used as a wall construction material. One of its main advantages is its light weight, which can help reduce overall construction costs. The reduced weight of the wall material allows for a decrease in the volume of structural elements needed. However, with advancements in material technology, there is a need to further improve the efficiency of lightweight bricks in terms of material usage and the quality of the masonry, particularly its shear strength. This research aims to analyze the optimal fiber placement composition in Cellular Lightweight Concrete (CLC) bricks to enhance the bond strength between bricks compared to that of standard lightweight brick masonry. The test specimens were constructed by assembling wall segments using lightweight bricks measuring 7.5 cm × 20 cm × 60 cm. Compressive strength and horizontal shear strength tests were then conducted on the CLC brick wall assemblies. The results showed that the lightweight bricks had a compressive strength of f'c = 1.07 MPa. The horizontal shear strength without fiber reinforcement was fg = 0.09 MPa, while with fiber reinforcement, it decreased to f'g = 0.06 MPa. Crack patterns were observed at failure displacements of 0.33 mm (non-fiber) and 0.5 mm (with fiber). These findings indicate that the use of GRC fiber in lightweight brick walls resulted in lower horizontal shear strength and displacement performance.
