Abstract

The earthquake that occurred in Pasaman on February 25, 2022, has caused considerable losses to local residents. Thousands of buildings have been damaged and collapsed due to the earthquake, especially houses of residents, which in the field investigations are caused mainly by a lack of knowledge in building these houses. This study aims to identify the level of damage to houses damaged by the earthquake in Nagari Malampah, Pasaman District, West Sumatera. This research method is carried out by direct observation and investigation of the research location, then identifying the level of damage to residents' houses, by taking 10 samples of affected residents' houses. Of the 10 houses, the percentage of damage will be grouped based on the level of Light Damage, Medium Damage, and Heavy Damage, with reference to the Technical Guidelines for the Director General of Human Settlements, SNI 1726-2019, and PU Guidelines. The results of this study indicate that the percentage of the level of damage to houses that are lightly damaged ranges from 7.1% - 26%, the level of moderate damage ranges from 32.5% - 36.09%, and the level of residential buildings that experience severe damage (total collapse) ranged from 50% - 100%.

Abstract

Penampang kolom adalah salah satu elemen penting dalam desain struktur beton bertulang. Berbagai bentuk penampang dapat digunakan, seperti persegi, persegi panjang, lingkaran, atau bentuk khusus lainnya. Setiap bentuk penampang memiliki karakteristik yang berbeda dalam hal kekuatan, kekakuan, dan perilaku ketika terkena beban. dilakukan analisis komparatif terhadap beberapa variasi bentuk penampang kolom beton bertulang. Metode analisis dinamik dan Perangkat lunak analisis struktur digunakan untuk mensimulasikan perilaku struktur dengan berbagai bentuk penampang. Parameter seperti beban maksimum yang dapat ditahan, deformasi struktural, dan gaya dalam kolom dievaluasi dan dibandingkan. Hasil penelitian didapatkan nilai simpangan arah X paling kecil dengan rasio 9,08% dari  kolom persegi dan 0,84% terhadap kolom lingkaran Simpangan arah-Y nilai paling kecil terjadi pada struktur dengan kolom lingkaran dengan rasio 15,15% terhadap kolom persegi panjang dan 7,40% terhadap kolom persegi. Nilai gaya geser arah X pada kolom persegi memiliki rasio 5,07% terhadap kolom lingkaran dan 6,2% terhadap kolom persegi panjang. Nilai gaya geser arah Y pada kolom persegi panjang memiliki rasio 15,5% terhadap kolom lingkaran dan 6,8% terhadap kolom persegi. Gaya momen arah Y pada kolom persegi panjang memiliki rasio 12,76% terhadap kolom lingkaran dan 7,66% terhadap kolom persegi, pada gaya momen arah X kolom persegi memiliki rasio 6,52% terhadap kolom lingkaran dan 7,5% terhadap kolom persegi panjang
