“…In an ECC/concrete repaired system, ECC may prevent early delamination or surface spalling [53]. ECC offers better fatigue resistance than traditional repair materials such as polymer cement [54]. Finally, the low rate of aggressive agent movement via ECC may postpone steel corrosion, resulting in longer service life in buildings in coastal areas.…”

Cementitious composites are one of the world's most consumed infrastructure construction materials because of their abundant resources, mature production process, and strong adaptability. Most of these materials, however, remain brittle. It highlights the need to develop low-cost, high-ductility cementitious materials for structural applications. These issues are the fundamental driving force behind Engineered cementitious composites (ECC) development due to the micromechanical interactions between its constituents and processing techniques. ECC is a high-performance, ultra-ductile fiber-reinforced cementitious composite material designed for high material volume and cost-sensitive applications in the construction sector. However, this material still lacks standardization regarding mix proportion and fiber used as a proper processing technique to balance economy and requirements for strength and durability. This paper aims to review some of the past researchers' design proportions and fiber types used as a reference and guide for future researchers utilizing ECC in their studies. This paper also covers ECC's results and target application in structural engineering.

“…Pengaruh lainnya yang berkerja optimal adalah adanya jarak yang tipis antara spiral dan area yang lebih besar dari beton di kolom komposit dapat menghasilkan kekuatan dan daktilitas yang lebih baik dari kolom tersebut (Liang et al, 2014). Tulangan baja melintang diperlukan sebagai bagian dari struktur yang memiliki kinerja tinggi karena memiliki daktilitas tarik tinggi dan ketangguhan tinggi (Hou et al, 2020).…”

Kolom merupakan salah satu komponen struktur utama dalam sebuah bangunan gedung yang berfungsi sebagai pemikul beban dari bagian atas dan meneruskannya sampai ke pondasi. Kekuatan sebuah gedung sangat didipengaruhi oleh kekuatan kolom. Kolom harus memiliki kapasitas yang baik diantaranya tahan terhadap bahaya tekuk akibat pembebanan. Desain kolom menjadi salah satu hal yang harus diperhatikan agar memiliki kapasitas yang sesuai dengan pembebanan. Dalam perkembangan saat ini, kolom tidak hanya menggunakan material beton atau baja saja akan tetapi banyak digunakan material komposit baja-beton. Material komposit baja-beton digunakan dengan tujuan untuk mendapat kombinasi keuntungan dari kedua material yaitu baja dan beton sehingga dapat meningkatkan kapasitas kolom. Oleh karena itu, penelitian ini bertujuan untuk menganalisis perilaku gedung dengan menggunakan kolom komposit dan non komposit. Penelitian dilakukan dengan memodelkan gedung yang sama dengan variasi kolom yang berbeda yaitu kolom dengan menggunakan material beton, baja dan komposit beton-baja. Gedung yang dimodelkan merupakan gedung 6 lantai dengan dimensi, peruntukan gedung dan pembebanan yang sama yaitu gedung rumah sakit. Hasil penelitian menunjukkan bahwa kolom komposit pada penelitian ini memiliki kapasitas terhadap momen dan geser yang lebih besar dari pada kolom nonn komposit

Reinforced concrete structures deteriorate due to changes in temperature, corrosion, and attacks of sulfate and chloride contents. Retrofitting techniques like fiber‐reinforced polymer (FRP) jacketing, known for their strength and corrosion resistance, are increasingly used to strengthen and retrofit deteriorated structural elements. Large rupture strain (LRS)‐FRP composite, composed of polyethylene terephthalate and polyethylene naphthalate, both of which have high tensile strength and high strain at rupture have been used in the studies of many researchers. This research aims to develop a reliable and accurate machine learning (ML) model to estimate the compressive strength of LRS‐FRP confined specimens. A total of 303 LRS‐FRP confined specimens were gathered after a thorough literature review to develop ML models, utilizing the linear regression, support vector regression, regression tree, and artificial neural network (ANN) algorithms. Additionally, 44 analytical models (AMs) were used to compare the performance of the developed ML models. The results revealed that the performance of the developed ANN model was higher among all the ML and AMs. The R‐value and the mean absolute percentage error (MAPE) value of the developed ANN model were 0.9822 and 6.17%, respectively. The sensitivity analysis results show that the height of the specimens had the highest impact followed by the diameter of the specimen, the number of FRP layers and thickness, and then the tensile strength of LRS‐FRP. The ANN‐based mathematical expression is simple and easy to use to predict the compressive strength of the LRS‐FRP strengthened specimens.
