17 Ağustos 1999 Kocaeli depreminde, Adapazarı şehir merkezinde dar cepheli, yüksek ve narin onlarca binanın hasar görmeden temeliyle birlikte devrildiği görülmüştür. Bu davranışın en büyük sebebi, deprem yüküne bağlı artan taban basıncı ile zemin taşıma kapasitesinin elastik yatak katsayısının aşılmasıdır. Binaların, zemindeki farklı oturmalardan kaynaklı tepe deplasmanları ikinci mertebe momen...

Optimal design of structures is one the goals a structural engineer. Since large number variables are involved, high computational time for optimization process main problems using single heuristic or meta-heuristic algorithms utilized this purpose, especially in large-scale structures. Cascade replaces problem with multiple stage process. Each step starts previous optimum design, being reduced...

Evaluation of structural performance in Indonesia has been carried out for several high-rise buildings as part the owner's demands safety guarantees to determine level security that building has. A simple but accurate nonlinear analysis is needed structure's under earthquake loads. The capacity spectrum method (pushover analysis) documented ATC 40 a form equivalent linearization based on two ba...

Special Plate Shear Wall (SPSW) merupakan struktur rangka yang terdiri dari pelat baja vertikal (infill plate) sebagai dinding pengisi tersambung dengan balok dan kolom, berfungsi untuk menahan beban seismik. Penelitian ini bertujuan mengetahui tingkat kinerja gedung SPSW terhadap variasi penampang kolom menggunakan metode analisis pushover bantuan software ETABS. Struktur klinik 6 lantai, tota...

Pada perencanaan struktur gedung, perhitungan beban lateral akibat gempa sangat diperlukan. Analisis respons spektrum adalah cara analisa hubungan antara periode bangunan dengan nilai percepatan ketika terkena gempa. Analisa statik ekuivalen biasa digunakan pada yang tidak terlalu tinggi, dimana pengaruh dianggap sebagai horisontal pergerakan tanah. Penelitian ini menggunakan objek gedung perku...

The widespread brittle failure of welded beam-to-column connections caused by the 1994 Northridge and 1995 Kobe earthquakes highlighted the need for retrofitting measures effective in reducing the strength demand imposed on connections under cyclic loading. Researchers presented the reduced beam section (RBS) as a viable option to create a weak zone away from the connection, aiding the preventi...
