“…Kibriya [6] showed a 300% to 400% increase in capacity using steel tube confined concrete columns. Lacki et al [7] investigated different cross-sections via FE-modeling, with both I-section profiles embedded in the concrete and hollow steel profiles as permanent molds for the concrete column. The approach with entirely confined concrete in hollow steel profiles seems to have been the most thoroughly investigated method [8] and used in many different applications [9].…”

To reduce the global emission of CO2 from the building industry, researchers, architects and manufacturers must consider new ways of constructing precast concrete buildings. Modern concrete columns and walls are not optimized to the applied load, and there is potential to save material. By creating a stronger column core and a lightweight concrete cover, it is possible to reduce the carbon footprint. A method is proposed to calculate such eccentrically loaded columns of two or more materials. The analytical method is developed for straight columns and columns with Entasis. Production of curved Entasis columns is possible by using textile molds due to the low mold pressure from the light aggregate concrete. Two column types are load tested to confirm the method. The CO2 emission is calculated for some column examples, and it shows that an optimized column geometry often leads to a reduced carbon footprint compared to regular columns. The concept is especially efficient for slender columns. Furthermore, the external light aggregate concrete layer ensures protection against fire if high-strength concrete is applied as the column core.

Concrete Filled Steel Tube (CFST) adalah pipa besi yang diisi dengan beton dan merupakan salah satu material alternatif untuk struktur bangunan sederhana. Disaat penggunaan baja Wide Flange (WF) dirasa melewati anggaran yang dibatasi oleh pemilik bangunan maka penggunaan kolom CFST bisa dijadikan pilihan. Pada pembangunan sebuah rumah tinggal dua lantai di daerah Bandung, pemilik bangunan dan kontraktor memutuskan untuk menggunakan material alternatif ini untuk mengurangi biaya konstrusi yang dibutuhkan. Kolom lantai dua dari bangunan ini menggunakan CFST sedangkan lantai dasar menggunakan baja Wide Flange (WF). Penelitian ini bertujuan untuk mengamati proses dilakukannya eksperimen penerapan kolom CFST pada bangunan rumah tinggal dua lantai tersebut. Keputusan membangun menggunakan kombinasi material ini telah dilakukan setelah melalui diskusi oleh pemilik, arsitek dan kontraktor. Penerapan kolom CFST pada bangunan rumah tinggal ini dilakukan dengan material pipa besi kotak ber SNI denan ukuran 10 cm x 10 cm dengan ketinggian 3 meter. Pengisian beton di dalam besi dilakukan dengan memadatkan campuran semen K225 dengan material konstruksi terbaik yang ada di wilayah pembangunan. Modul struktur yang digunakan adalah 3 m x 3 m dengan metode konstrusi menggunakan teknik sederhana yaitu menyambung kedua material dengan plat dan sambungan pengelasan. Plat baja yang digunakan berukuran 15x30 cm juga diberi angkur berukuran sama. Pekerjaan kolom CFST ini tidak memerlukan bekisting sehingga dapat menghemat waktu dan tenaga kerja. Pada tahap finishing arsitektural pekerjaan juga menjadi lebih mudah karena dimensi kolom CFST berukuran sama dengan batu bata dinding pengisi. Hasil penelitian menunjukkan penerapan kolom CFST pada rumah tinggal ini terbukti dapat dilaksanakan lebih cepat dan murah dibandingkan penggunaan material bangunan rumah tinggal konvensional.

The axial compressive performance of steel-reinforced concrete columns with monosymmetric cross-shaped steel (SRCC-MCS) was investigated in this study. Tests were conducted under pure axial compression to determine the effects of cross-shaped steel eccentricity ratio, concrete strength, steel ratio, and stirrup spacing on the resulting failure mode, load-strain curves, and load-displacement curves. The results indicated that increasing the cross-shaped steel eccentricity ratio reduced the axial capacity and ductility, increasing the concrete strength markedly enhanced the axial capacity but reduced the ductility, and increasing the steel ratio and reducing the stirrup spacing increased the axial capacity and ductility. Two calculation methods for determining the axial capacity of an SRCC-MCS under axial compression were proposed considering the effective lateral confinement pressures provided by the stirrups and monosymmetric cross-shaped steel. The proposed equations were compared with those in three extant codes and found to exhibit improved accuracy and consistency.
