Abstract

Reinforced concrete shear wall (RC wall) is an important element in tall buildings, which provides strength and stiffness against lateral loadings, e.g. earthquake and wind. Numerous researches have been conducted to study its nonlinear behavior via microscopic and macroscopic model. The later approach is currently being widely explored since it has many advantages compared to the preceding models. A well-known macroscopic model, namely Shear-Flexure-Interaction Multiple-Vertical-Line-Elements-Model (SFI-MVLEM) in the open source platform Open Sees, is capable of simulating the coupled nonlinear shear-flexure interaction response in the RC wall. This paper presents an evaluation to the applicability of SFI-MVLEM model to predict the coupled nonlinear shear-flexure behavior of RC wall specimens compared to experimental results in available literature. The analysis results show that the model is able to predict the behavior of RC wall considerably accurate in terms of hysteretic curves, cracking patterns, and contributions of shear and flexural displacement to total displacement.

Abstract

Kecelakaan lalu lintas merupakan salah satu permasalahan serius yang berdampak besar terhadap keselamatan masyarakat. Penelitian ini bertujuan untuk menganalisis hubungan antara jumlah kecelakaan dan tingkat fatalitas kecelakaan lalu lintas di ruas Jalan Sudirman, Kota Maumere. Data yang digunakan meliputi data sekunder kecelakaan dari Kepolisian Resor Kabupaten Sikka tahun 2019–2023, serta data primer berupa volume lalu lintas dari hasil survei lapangan. Metode analisis yang digunakan adalah analisis regresi linier sederhana dan korelasi untuk mengetahui kekuatan dan arah hubungan antar variabel. Hasil analisis menunjukkan bahwa terdapat hubungan positif linear yang cukup kuat antara jumlah kecelakaan dan tingkat fatalitas, dengan nilai koefisien determinasi (R²) sebesar 0,6722. Artinya, sekitar 67,22% variasi tingkat fatalitas dapat dijelaskan oleh perubahan jumlah kecelakaan. Temuan ini menunjukkan bahwa peningkatan jumlah kecelakaan secara signifikan berkontribusi terhadap peningkatan risiko fatalitas di lokasi penelitian. Penelitian ini diharapkan menjadi acuan dalam perencanaan dan pengendalian keselamatan lalu lintas di wilayah perkotaan.
