Abstract

Ductility is one of the main criteria in reinforced concrete (RC) structures. ASCE 7-10 seismic design code recognizes the importance of ductility in earthquake-resistant structures. The structures need to be designed to have sufficient strength and ductility for overall safety against earthquake forces. Both the strength and the ductility are mutually associated to enhance structural seismic safety in this study. Previous studies showed that a shear wall gives different performance based on its position in building structures. This paper presents the position of the shear walls and shear wall thicknesses effects on ductility. A total of 96 two-dimensional (2D) models are analyzed for this work using ETABS software. The non-linear static analysis (pushover) method is used to analyze and design these RC building structures with shear walls. It is concluded that an increase in shear wall thickness causes a decrease in ductility values, and a decrease in ductility value will also occur when the shear wall position changes from edge to middle.

ABSTRAK: Kemuluran adalah salah satu kriteria utama dalam struktur konkrit bertulang (RC). Kod reka bentuk ASCE 7-10 seismik dunia menyedari pentingnya kemuluran dalam struktur tahan gempa. Struktur perlu dibina bagi mencapai ketahanan kekuatan dan kemuluran yang mencukupi bagi keselamatan keseluruhan terhadap kekuatan gempa. Kekuatan dan kemuluran dihubungkan bersama bagi meningkatkan keselamatan tahan gempa dalam kajian ini. Kajian sebelumnya menunjukkan bahawa dinding ricih memberikan prestasi yang berbeza berdasarkan kedudukannya dalam struktur bangunan. Kertas ini menunjukkan kedudukan dinding ricih dan ketebalan dinding ricih kesan pada kemuluran. Sebanyak 96 model dua dimensi (2D) dianalisis dalam kajian ini menggunakan perisian ETABS. Kaedah analisis statik bukan linear (pushover) digunakan bagi menganalisis dan merancang struktur bangunan RC ini dengan dinding ricih. Kesimpulannya peningkatan ketebalan dinding ricih menyebabkan penurunan nilai kemuluran, dan penurunan nilai kemuluran juga akan terjadi ketika posisi dinding ricih berubah dari tepi ke tengah.
