Fly slab is a reinforced concrete mixture designed using high quality technology to produce concrete that is more effective, efficient and economical than conventional concrete. The concept is to reduce the mass of a precast concrete floor plate by making ribs on a concrete floor plate. By minimizing the volume of concrete in the tensile area of the floor plate while maintaining the mechanism of force transfer from concrete to reinforcement or on other contrary, it is expected to reduce the mass of the structure without reducing its strength. The objective of this research is to find out how much the efficiency of material requirements in planning earthquake resistant building structures using fly slab plates. The results of the analysis showed that the total weight reduction was 18.46% and the total concrete volume reduction was 26.53%. Reduction of structure vertical reaction was 30.78%.

Experimental study on reinforced concrete strengthening with CFRP has been conducted to estimate the effectiveness of using CFRP on the concrete structure as flexural strengthening material and external reinforcement. In this research, three specimens were tested. The first specimen is the reinforced concrete beam with single steel reinforcement (BT), which is used as control beam. The second specimen is the reinforced concrete beam with single steel reinforcement and laminated CFRP (BTF). The last specimen is the concrete beam with laminated CFRP without steel bar (BF). The second and third beam, CFRP laminated on the bottom of beam with epoxy. Dimension of the beams are 150/250 mm with effective length 1900 mm. All beams were tested using four-point loading to get pure bending in the middle span. The result of the experimental research showed that the ultimate load of the strengthened beams BTF is 49% higher than BT; stiffness of the strengthened beam BTF is 68% higher than BT; and cracking moment of the strengthened beam BTF is 50% higher than BT. However, the deformation and ductility of the strengthened beam BTF is lower than BT 77.6% and 73% respectively. In spite of using laminated CFRP on the concrete beam (BF) may increase the stiffness 33.3% and cracking moment 50%, but using laminated CFRP on the concrete beams as external reinforcement without reinforcing steel bar (BF) is not effective, because the strain of CFRP is only 41% of the maximum strain that may be reached. The failure phenomenon of the concrete beam with laminated CFRP (BTF san BF) is prior de-bonding CFRP that makes maximum performance of the CFRP not be reached.

This is a particular concern for structural experts in planning buildings vertically to save space. Therefore earthquake-resistant building planning is needed. The design of a building with a swimming pool on the top level of the building, especially on the roof floor, has become one of the trends in society, commonly known as an infinity pool. Structurally, a building with a swimming pool on the top floor must be given special attention. The swimming pool on the top floor, especially on the roof floor of the building, unquestionably burdens the building. In planning for earthquake-resistant buildings, it refers to the latest SNI, namely SNI 1726: 2019 Procedures for Planning for Earthquake Resistance for Building and Non-Building Structures and 2847: 2019 Requirements for Structural Concrete for Buildings and Explanations

This study aims to determine the strength of concrete by adding fly ash as a substitute for cement in high-strength concrete mixtures. This research was conducted using an experimental method to obtain results and data that would confirm the variables studied. The total numbers of specimens used in this study were 36 pieces with different sizes of cube tests which were 15 cm x 15 cm x 15 cm. A total of 36 concrete samples were used to test the compressive strength of concrete with a percentage of Fly Ash in 0% (normal concrete), 20%, 25% and 30% with a concrete treatment age of 7 days, 21 days and 28 days. A total of 12 more samples were used to test water absorption in concrete at 28 days of maintenance. Each percentage of Fly Ash uses 3 concrete test samples. The increase in compressive strength occurs at 7, 21 and 28 days in concrete. However, the compressive strength of concrete produced by concrete using the percentage of Fly Ash is always lower than the value of normal concrete compressive strength. From testing the compressive strength of concrete at 28 days of treatment with

Fly slab is a reinforced concrete mixture designed using high quality technology to produce concrete that is more effective, efficient and economical than conventional concrete. The concept is to reduce the mass of a precast concrete floor plate by making ribs on a concrete floor plate. By minimizing the volume of concrete in the tensile area of the floor plate while maintaining the mechanism of force transfer from concrete to reinforcement or on other contrary, it is expected to reduce the mass of the structure without reducing its strength. The objective of this research is to find out how much the efficiency of material requirements in planning earthquake resistant building structures using fly slab plates. The results of the analysis showed that the total weight reduction was 18.46% and the total concrete volume reduction was 26.53%. Reduction of structure vertical reactio...

Experimental study on reinforced concrete strengthening with CFRP has been conducted to estimate the effectiveness of using CFRP on the concrete structure as flexural strengthening material and external reinforcement. In this research, three specimens were tested. The first specimen is the reinforced concrete beam with single steel reinforcement (BT), which is used as control beam. The second specimen is the reinforced concrete beam with single steel reinforcement and laminated CFRP (BTF). The last specimen is the concrete beam with laminated CFRP without steel bar (BF). The second and third beam, CFRP laminated on the bottom of beam with epoxy. Dimension of the beams are 150/250 mm with effective length 1900 mm. All beams were tested using four-point loading to get pure bending in the middle span. The result of the experimental research showed that the ultimate load of the strengthened beams BTF is 49% higher than BT; stiffness of the strengthened beam BTF is 68% higher than BT; and cracking moment of the strengthened beam BTF is 50% higher than BT. However, the deformation and ductility of the strengthened beam BTF is lower than BT 77.6% and 73% respectively. In spite of using laminated CFRP on the concrete beam (BF) may increase the stiffness 33.3% and cracking moment 50%, but using laminated CFRP on the concrete beams as external reinforcement without reinforcing steel bar (BF) is not effective, because the strain of CFRP is only 41% of the maximum strain that may be reached. The failure phenomenon of the concrete beam with laminated CFRP (BTF san BF) is prior de-bonding CFRP that makes maximum performance of the CFRP not be reached.
