Abstract
Pracetak jika ditinjau dari segi pelaksanaan konstruksi, lebih efektif dan efisien dari beton konvensional. Rumah pracetak yang diteliti terdiri dari Rumah Tidak Bertingkat (RTB) luas 36 m2 dan Rumah Bertingkat {RBT) luas 66m2, sistem rangka berdinding pengisi dan sistem rangka terbuka yang dianalisis team. Disini penelitian difokuskan pada perilaku dan perancangan kolom bangunan sistem rangka terbuka Sebelum menetapkan dimensi dan tulangan yang digunakan, analisis dimulai dengan dimensi yang lebih kecil dengan coba-coba, karena kolom harus didisain dengan Strong Column Weak Beam, jadi disain kolom berhubungan dengan disain balok serta dipengaruhi oleh hubungan balok kolom. sehingga ditentukan penulangan longitudinal yang optimum untuk RTB WG 6 dan 4, dimensi 150 x 150 mm tulangan longitudinal4-Dl6, RBT WG 6 dan 4 dimensi kolom 250 x 250 mm2 , tulangan longitudinal 8-D16. Hasil Xtract untuk daktilitas kolom menunjukan elemen kolom dengan jarak tulang sengkang 90 mm diameter 8 mm yang optimum dengan nilai kurvatur lebih dari 16. Dari analisis Xtract RTB nilai J!q, = 16,36, RBT nilai JJ.q, = 19,36. Performance disain struktur dari analisis pushover SAP 2000 menunjukan perilaku struktur tahan gempa berbasis kinerja, terjadi pelehan balok terlebih dahulu. Daktilitas perpindahan struktur juga mampu lebih dari 5,3 yaitu RTB = 8, RBT = 11,33. Analisis Lusas 13.5 menunjukan kolom sangat kuat menerima beban dari kombinasi beban mati, beban hidup dan beban gempa. Supaya pelaksanaan struktur cepat, sambungan dirancang dengan menggunakan dry joint. Didisain dengan beban dari kapasitas kolom dianalisis dengan Lusas 13.5 dan Xtraxt. Dirancang empat sambungan kolom dengan kolom atau pondasi yaitu : sambungan kolom pendek baja, sambungan pelat dasar mengunakan baut, sambungan pelat dasar menggunakan las dan sambungan mekanis menggunakan FD Grip, dari keempat sistem sambungan yang ada dipilih FD Grip karena harga termurah, ringan dan cepat pelaksanaannya

Precast when viewed from the construction implementation perspective, is more effective and efficient than conventional concrete. The precast houses studied consisted of Non-Storey Houses (RTB) with an area of 36 m2 and Storey Houses (RBT) with an area of 66m2, a frame system with infill walls and an open frame system analyzed by the team. Here the research is focused on the behavior and design of open frame system building columns. Before determining the dimensions and reinforcement used, the analysis begins with a smaller dimension by trial and error, because the column must be designed with Strong Column Weak Beam, so the column design is related to the beam design and is influenced by the beam-column relationship. so that the optimum longitudinal reinforcement is determined for RTB WG 6 and 4, dimensions 150 x 150 mm longitudinal reinforcement 4-Dl6, RBT WG 6 and 4 column dimensions 250 x 250 mm2, longitudinal reinforcement 8-D16. Xtract results for column ductility show column elements with a stirrup distance of 90 mm and a diameter of 8 mm which is optimum with a curvature value of more than 16. From the Xtract RTB analysis, the value of J!q, = 16.36, RBT the value of JJ.q, = 19.36. The structural design performance of the SAP 2000 pushover analysis shows the behavior of earthquake-resistant structures based on performance, beam yielding occurs first. The displacement ductility of the structure is also capable of more than 5.3, namely RTB = 8, RBT = 11.33. The Lusas 13.5 analysis shows that the column is very strong in receiving loads from a combination of dead loads, live loads and earthquake loads. In order for the implementation of the structure to be fast, the connection is designed using a dry joint. Designed with loads from the column capacity analyzed with Lusas 13.5 and Xtraxt. Four column connections were designed with columns or foundations, namely: short steel column connections, base plate connections using bolts, base plate connections using welding and mechanical connections using FD Grip. Of the four existing connection systems, FD Grip was chosen because it is the cheapest, lightest and quickest to implement
