The strengthening mechanism is presented and implemented to verify its availability. Three brick wall specimens were prepared and tested with/without strengthening. As a result, the proposed method significantly improved the structural performance of walls in the out-of-plane direction. Moreover, in this paper, a theoretical calculation procedure is presented for the performance evaluation. The out-of-plane performance of the strengthened specimens was reasonably evaluated through the procedure.

Tuna bone fibers work as reinforcement, which is expected to overcome the problem of brittle concrete and produce ductile concrete. To improve concrete performance, fibers and additives are used. Tuna bone fibers and rice husk ash additives were selected to be able to utilize local natural materials. The purpose of this study is to examine the mechanical properties of normal concrete, which include compressive strength and tensile strength, by adding fiber and ash additives. The percentage of fibers added is 0%, 0.5%, 1%, and 1.5% of volume of concrete, and the percentage of additives is 0%, 10%, and 15% of weight of cement. Compression tests were performed to a total of 90 pieces of objects at 7, 28, and 56 days of age. Split tensile tests were performed to a total of 60 pieces of objects at the 28 and 56 days of age. The maximum compressive strength at 7, 28, and 56 days of age are 31.45 MPa, 36.81 MPa, and 41.16 MPa, respectively which were produced by variation BNS1 (BN+fiber 0.5%). The maximum tensile strength at 28 and 56 days of age are 4.08 MPa and 4.12 MPa; respectively which were produced by variation of BNS2 (BN+fiber 1%). All specimens at 7, 28, and 56 days of age produce concrete compressive strength on average 20 MPa of concrete above so that it is categorized into structural concrete.

Uniform distributed loads are applied to masonry walls by a rubber airbag. The test system was developed aiming at obtaining basic mechanical characteristics of simply supported masonry walls in the out-of-plane direction. In this study, two kinds of structural tests were conducted (a) to verify the developed loading system by using an aluminum plate specimen, and (b) to evaluate the out-of-plane performance of a brick wall specimen. Consequently, the test results clarified (a) good agreements between the experimental measurements and theoretical estimations, and (b) vulnerability of the brick wall.

In this area, peoples commonly use the brick masonry as infill in the Reinforced Concrete (RC) frame structures. Field investigation after the earthquake informed that there were many bricks masonry infill collapsed caused by the earthquake motion. In this study, a simple and safe brick masonry infill construction in the RC frame structure is proposed for applying in the high seismic-prone area such as West Sumatera. The proposed construction method was defined based on the experimental works of the three 1/4 reduced-scale singe-bay and single-story RC frame specimens. The specimens include one specimen of RC frame infilled with brick masonry, one specimen of RC frame infilled with strengthened brick masonry by using chicken wire mesh, and one specimen of RC frame infilled with brick masonry infill and anchored to the columns with plain steel rebars. The wire mesh was sewn on both sides of the diagonal area of the brick masonry infill. All the specimens have subjected to lateral static reversed loading. The structural test results have shown that the strengthening using the chicken wire mesh increase the lateral strength of the RC frame about 22.%, while the use of the plain rebars anchor decreases the lateral strength about 1.8% and both methods can delay the failure of the brick masonry infill.

Reventing brittle hybrid high-strength reinforced concrete slab collapse due to punching shear using coal flyash substitution, tie wire fiber and polypropylene fiber

IOP Conference Series: Materials Science and Engineering, 2021

Heavy vehicles crossing a bridge could lead in punching shear failure at reinforced concrete deck... more Heavy vehicles crossing a bridge could lead in punching shear failure at reinforced concrete deck slab due to highly concentrated axial compressive load from their wheels. This may occur in a very brittle manner and difficult to fix. Effort in improving punching shear capacity of deck slab is with using high-strength concrete and adding fibers into concrete. However, high-strength concretes are not environmentally friendly because using a lot of cement contributing to large CO2 emissions to the atmosphere during its production, therefore coal flyash is used as a part of cement substitution. Based on these facts, this research aims to analyze punching shear capacity of hybrid high-strength reinforced concrete slabs using coal flyash as cement substitution which added with tie wire fiber and polypropylene fiber. The amount of coal flyash was taken 15% from cement weight as cement substitution, tie wire fiber 2% from concrete volume having aspect ratio l/d of 40 and straight shaped fib...

In the past studies, an analytical method of diagonal strut model has developed for evaluating the seismic performance of masonry infill. In this model, the masonry infills were presented by compression struts as distributed forces at the frame-infill interfaces in which the frame-infill contact lengths were evaluated by static equilibrium related to compression balance and lateral displacement compatibility. The lateral strength of infill was determined based on frame-infill contact length. In the current study, an experimental study of quasi-static cyclic lateral loading tests was conducted to evaluate the seismic performance of two-bay brick masonry infilled RC frames. This paper discusses the results of seismic performance brick infills based on experimental and analysis results of the multi-span maso...

Called Interlocking Brick or Brick Interlock because the method of arranging the bricks is interlocked with one another. This interlocking brick itself began to be known in Aceh Province after the 2004 tsunami disaster. Interlocking brick is a block of compacted soil, made of cement, silt soil, and dried sand, measuring 300 χ 150 χ 100 cm3. Interlocking brick can function as a wall that can withstand structural and non-structural components. The purpose of this research is to get the compressive strength value of interlocking bricks designed with variations in the water cement ratio (WCR) so that the optimum compressive strength of interlocking bricks is obtained. The WCR used was 0.3; 0.4; and 0.5, while for the composition of cement, silt, and sand the ratio of 1:2:2 is used. The making of test specimens for testing the compressive strength of interlocking bricks is by cutting the interlocking bricks into cu...

Changes in unit prices are possibly determined by the different sites in which a building is constructed. For budget planners or construction executors, a good understanding of the changes in the unit price of work is required to identify the reasonable amount of budget needed. Given these circumstances, this study was conducted to analyse and identify the pattern of changes in the unit price of work based on the locations of a building in the Province of Aceh. This research focuses on the unit price of reinforced concrete work for the building structure components, as the work that has the most significant proportion of cost in building construction. The pattern of change is described in the form of price indexes by applying the price in Banda Aceh City as a reference for other cities/districts. The analysis re...

In the development of building materials technology and cost savings, interlocking brick can be alternative to replace red bricks. In Aceh Province, the use of interlocking bricks is less popular compared to other big cities in Indonesia. Interlocking brick is made from a mixture of clay, concrete sand and compacted cement and one of the environmentally friendly materials because it does not burn the process like red brick material. It is named interlocking brick because the installation method is locked together and it serves as a structural and partition wall of residential buildings. The aims of this study are to compare the cost of building a house in Banda Aceh City using red brick and interlock brick building materials. The data were obtained from interviews and questionnaires distributed to respondents who had built houses in Banda Aceh City. The results concluded that the house construction cost using interlock brick offer lower construction cost at comparable quality rather than using red brick.
