Abstract

Hotel dirancang menyerupai rumah panggung yang merupakan rumah khas bagi masyarakat Bugis-Makassar. Material struktur yang dipilih adalah kayu Libung karena ringan, dan fleksibel. Struktur bangunan dimodelkan menjadi Model 1 (konvensional) dan Model 2 (link). Beban gempa menggunakan analisis riwayat waktu. Analisis riwayat waktu dengan empat beban gempa referensi yang diskalakan dapat digunakan untuk memberikan gambaran gaya lateral yang bekerja pada bangunan. Struktur kayu tersebut dievaluasi terhadap parameter gaya geser dasar, simpangan antarlantai, dan taraf kinerja struktur. Taraf kinerja struktur mengacu pada ATC-40 yang ditentukan dari rasio maximum total roof displacement terhadap ketinggian struktur. Model struktur dengan link memiliki nilai periode lebih besar daripada struktur model konvensional, karena memiliki kekakuan sambungan balok-kolom yang lebih rendah. Model struktur dengan link memiliki gaya geser dasar akibat gempa lebih rendah, namun simpangannya lebih besar. Nilai rasio maximum drift terhadap tinggi total struktur akibat empat gempa yang ditinjau memiliki nilai rasio lebih kecil 0,010 sehingga taraf kinerja struktur adalah immediate occupancy.

Abstract

Indonesia's geographical location makes Indonesia as a country prone to earthquake risks, both tectonic as well as volcanic. The Indonesian National Standard (SNI) 1729:2015 requires bolt connections for steel buildings with a height of more than 38 m must use high-strength bolts (HSB) with pre-tensioning. Snug-tight and pre-tensioned bolted connections are physically no different. Differences will occur when the connection is loaded, namely for pre-tensioned joints, where slip between the plates being joined as a result of the bolt hole size being larger than the bolt diameter will occur when the slip limit strength is exceeded. This study aims to observe the strength and behavior of pre-tensioned bolted joints with increasing loads. The analysis was carried out according to SNI 1729:2015, with data validation through experimental tests using BJ37 plate specimens loaded with concentric axial tension. The connection uses a HSB-A325 M12 standard hole with class A surface preparation. Pre-tension bolts are applied by turn-of-nut. The test results show that the strength of the slip limit (Pslip) is 37.998 kN; this value is 5.7% higher than the analytical result of 35.94 kN. After reaching the slip limit strength, the connection can still accept the load with the bearing force transfer mechanism and reach the connection limit strength (Pu) of 50.197 kN, 32% exceeding the slip limit strength. Turn-of-nut, one of the methods recommended by SNI 1729:2015, is a fairly simple method for pre-tensioning because no special additional tools are required and the required minimum pre-tensioning force can be met by achieving Pslip experimental results not lower than the results of the analysis.
