Abstract

Pada bangunan tinggi tahan gempa umumnya gaya – gaya pada kolom cukup besar untuk menahan beban gempa yang terjadi sehingga umumnya perlu menggunakan elemen – elemen struktur kaku berupa dinding geser untuk menahan kombinasi gaya geser, momen dan gaya aksial yang timbul akibat gempa. Dengan adanya dinding geser sebagian besar beban gempa akan terserap oleh dinding geser tersebut. Dinding geser adalah dinding yang dirancang untuk menahan geser atau gaya lateral akibat gempa bumi. Untuk merencanakan dinding geser ini menggunakan acuan SNI 2847:2013, untuk perencanaan gempanya menggunakan SNI 1726:2012 dengan menggunakan metode lateral ekivalen. Untuk perhitungan gaya-gaya yang pada struktur digunakan alat bantu SAP 2000. Dalam Perencanaan Dinding Geser ini diperoleh hasil data pekerjaan yaitu direncanakan dengan lebar. Lebar dinding geser (lw) = 550 cm. Tebal dinding geser, (tw) = 25 cm. Serta tulangan pada Dinding Geser. Tulangan vertikal atau tulangan longitudinal = 60 D 16. Tulangan horizontal atau tulangan transversal (sengkang) = Ø 12 -150. Tulangan horizontal atau tulangan transversal (sengkang) pada sendi plastis dan pada sambungan lewatan tulangan vertikal = Ø 12 -150. Sambungan lewatan, Id = 650 mm. Perbedaan hasil deformasi yang diperoleh yaitu bangunan yang tidak menggunakan dinding geser mengalami deformasi sebesar 0.047 mm dan bangunan yang menggunakan dinding geser mengalami deformasi sebesar 0.026 mm.

Abstract

Abstract. The rapid development of construction and infrastructure results in increasing demands for natural resources continue. One of the many natural elements required for construction and infrastructure activities was cement, which is the basic ingredient in concrete. This study aims to analyze the unit weight of foam concrete containing blended cement and fly ash. The research approach used in this study was a laboratory experiment. Foam concrete was produced using 4 variations of cement (OPC, PCC-T, PCC-B and OPC+FA), fine aggregate, water and foam. The shape of the test object used was cube with a size of 15 cm × 15 cm × 15 cm. Unit weight test was used to evaluate the foam concrete mixture produced at the age of 3, 7, 28 and 730 days. The results showed that the unit weight of foam concrete in all variations of the specimens: OPC, PCC-T, PCC-B and OPC+FA, met the requirements for the unit weight of lightweight structural concrete based on SNI 03-3449-2002 and ACI 213R3 which was between 800 to 1400 kg/m3.

Abstract

Innovations in material technology are expected to reduce the use of commercial cement and replace it with other environmentally friendly materials with the same performance as normal concrete. Aim: This study aim to analyze the mechanical property of High-Volume Fly Ash Concrete (HVFAC) using F class fly ash with different mix percentages. Methodology and Results: The experiment was conducted in laboratory scale. Four variations of test specimens consisted of: 1 variation (F0), which is conventional concrete with 100% Portland cement as control specimen, and three variations of HVFC (F70, F80, and F90), which were made with fly ash content (%) 70, 80, and 90 of total cementitious. Fresh concrete testing to determine workability, while hard concrete testing is done by density and compressive strength tests at the age of 3, 7, and 28 days on specimens that have been treated with the water submerged curing method. Conclusion, significance, and impact of study: All HVFAC specimens fulfill the Self Compacting Concrete (SCC) category. The compressive strength test results at 28 days showed that the addition of fly ash percentage caused a decrease in compressive strength values in all HVFAC variants, but still exceeded the minimum requirements of high and medium quality concrete. All HVFAC variations meet the requirements of ASTM C618-23 based on the evaluation of Strength Activity Index (SAI) values at 7 and 28 days of age. The utilization of 90% fly ash as a cement substitute resulted in an environmentally friendly concrete product based on the concept of cleaner production.

Abstract

Many researchers' interest in carbon nanotube (CNT) materials has grown as a result of their potential use in the construction industry. This is mostly related to the mechanical, electrical, thermal, kinetic, and chemical properties of CNT, which have a big impact on the way concrete functions. Hydrated calcium silicate is a complex network of binding particles that compose the cement composite material known as concrete. Since it has nanoscale features, CNT will interact most strongly with hydrated calcium silicate, improving the concrete's mechanical qualities. The purpose of this study is to ascertain the impact of adding CNT to concrete mixtures. Three distinct mixes were created by varying the types and amounts of admixtures that were added to the concrete mix.  Two mixed variations employed CNT at various doses, while one mixed variation used admixture type F (superplasticizer), and the performance of one was compared to the other. Concrete that was both new and hard underwent specimen testing. On fresh concrete, a slump test was conducted using ASTM C163, while for hard concrete, cylindrical specimens measuring 100 mm x 200 mm were tested for unit weight and compressive strength at 7, 14, and 28 days following ASTM C39. According to the test results, utilizing CNT at a lower dose than the typical superplasticizer dose leads to greater workability and compressive strength. The results of the workability and compressive strength tests will be improved by the inclusion of CNT.
