Theophilus, Stefan (2016) Pengaruh Rasio Tulangan Longitudinal dan Jarak Sengkang Terhadap Kapasitas Beban Lateral Maksimum Kolom Bertulangan Ringan Akibat Beban Siklik. Sarjana thesis, Universitas Brawijaya.
Abstract
Kolom merupakan komponen struktural yang berfungsi sebagai penerus beban seluruh bangunan ke pondasi. Di Indonesia masih sering dijumpai bangunan dengan kolom berrasio tulangan longitudinal kurang dari 0.01 kali luas bruto penampang atau bisa disebut kolom bertulangan ringan. Kolom bertulangan ringan seringkali dipercaya memiliki performa yang buruk dalam menahan gempa. Padahal di beberapa kasus yang ditemui bahwa di banyak negara, walaupun kolomnya bertulangan ringan, mereka cukup mampu bertahan terhadap gempa. Apabila ditinjau dari bidang ketekniksipilan, perlu adanya penelitian lebih lanjut mengenai kolom tulangan ringan tersebut dengan dikaitkan dengan aspek-aspek konstruksi. Aspek-aspek tersebut diantaranya adalah mengenai kekuatan struktur kolom tulangan ringan beserta komponen penyusunnya, daktilitas, kuat kapasitas beban lateral, ketahanan terhadap gempa, pola retak dan lain sebagainya Dalam penelitian ini kolom beton bertulang digunakan sebagai benda uji dengan banyak benda uji sebanyak 4 buah kolom dengan variasi rasio tulangan longitudinal (0,8% dan 1,1%) dan variasi jarak sengkang (15cm dan 25 cm). Kolom benda uji diletakkan diatas frame pengujian. Beban lateral siklik dan beban aksial yang juga akan dianalisa kapasitas beban lateral terhadap perpindahan. Hasil dari penelitian dan pembahasan data menjelaskan bahwa benda Uji L25C ( = 0.8% ; 6-250) dapat menahan 2270,5 kg saat kondisi push dan 1778,5 kg pada kondisi pull. Benda Uji L15C ( = 0.8% ; 6-150) dapat menahan 1508,5 kg saat kondisi push dan 2061,25 kg pada kondisi pull. Benda Uji M25C dapat menahan 2080 kg( = 1,1% ; 6-250) saat kondisi push dan 2322,5 kg pada kondisi pull . Benda Uji M15C dapat menahan 2202,5 kg ( = 1,1% ; 6-150) saat kondisi push dan 2079,5 kg pada kondisi pull.
English Abstract
Column is a structural component that serves as the successor to load the entire building to the foundation. In Indonesia, is still frequently encountered in buildings with column which longitudinal reinforcemen ratiot is less than 0.01 times the area of the gross cross-section or can be called lightly reinforced column. Lightly Reinforced Column is often believed that has a poor performance in withstand earthquakes. Whereas in some cases that was found in many countries , although column has light reinforcement , they are quite able to withstand earthquakes. When viewed from engineering study, need further research on lightly reinforcement columns with construction aspects. Thee aspects are structure power of lightly reinforced column and its components, ductility, lateral load capacity, resistance to earthquakes , crack patterns. In this study, reinforced concrete column is used as a specimen with 4 column with longitudinal reinforcement ratio ( 0.8 % and 1.1 % ) and confinement spacing ( 15cm and 25cm ) variation. Column test object is placed on the test frame. Lateral cyclic load and axial load capacity will be given then will be analyzed its lateral load against displacement. Results from the study and discussion of the data explains that the test object L25C ( = 0.8 % ; 6-250 ) can withstand 2270.5 kg in push condition and 1778.5 kg in pull condition. Test objects L15C ( = 0.8 % ; 6-150 ) can withstand 1508.5 kg in push condition and 2061.25 kg in pull condition . Test objects M25C can withstand 2080 kg ( = 1.1 % ; 6-250 ) in push condition and 2322.5 kg in pull condition . Test object M15C can withstand 2202.5 kg ( = 1.1 % ; 6-150 ) in push and l 2079.5 kg in pull condition
