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.
延性是钢筋混凝土(RC)结构的主要指标之一。ASCE 7-10抗震设计规范认识到延性在抗震结构中的重要性。结构的设计需要有足够的强度和延展性，以保证整体抗震安全。在本研究中，强度和延性是相互关联的，以提高结构的抗震安全性。以往的研究表明，剪力墙在建筑结构中的位置不同，其性能也不同。本文介绍了剪力墙位置和剪力墙厚度对延性的影响。利用ETABS软件对96个二维(2D)模型进行分析。采用非线性静力分析方法对具有剪力墙的钢筋混凝土建筑结构进行了分析和设计。结果表明，剪力墙厚度的增加会导致延性值的降低，当剪力墙位置由边缘向中间变化时，延性值也会降低。摘要:Kemuluran adalah salah satu kriteria utama dalam struckturr konkrit bertulang (RC)。Kod reka bentuk ASCE 7-10级地震，地震发生在塔罕地震。这是一种很好的学习方式，它可以帮助你学习，也可以帮助你学习。Kekuatan dan kemuluran dihubungkan bersama bagi meningkatkan keselamatan tahan gempa dalam kajian ini。Kajian sebelumnya menunjukkan bahawa正在寻找富有成员的prestasi yang berbeza berdasarkan kedudukannya dalam struktur bangunan。Kertas ini menunjukkan kedudukan表示富有，但ketebalan表示富有，kesan pada kemuluran。Sebanyak 96模型二维(2D)分析。Kaedah分析statik bukan linear (pushover)， digunakan, bagi, menganalysis, danmerancang, struct, banunan, RC, denengan, dinding, rich。kespulpulannya peningkatan ketebalan ding rich menyebabkan penurunan nilai kemuluran, dan penurunan nilai kemuluran juga akan terjadi ketika posisi ding rich berubah dari tepi ke tengah。
