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.

“…Otros estudios se han enfocado en la optimización de edificios de C/R utilizando la confiabilidad estructural; Ozkul et al (2019) evaluó la confiabilidad estructural de dos edificios de C/R con muros de cortante utilizando análisis no lineales paso a paso y sometidos a un evento sísmico, el sismo de Van 2011 en Turquia. Tuken, Dahesh y Siddiqui (2017) proponen utilizar una confiabilidad objetivo para un evento sísmico extremo, consecuentemente es necesario que el muro de cortante tenga una confiabilidad estructural mínima.…”

En el presente trabajo se compara la confiabilidad estructural de un edificio de concreto reforzado destinado a uso de oficinas y ubicado en el suelo blando de la Ciudad de México, utilizando dos sistemas estructurales distintos. El primero es a base de marcos resistentes a momento de concreto reforzado (sistema convencional) y en el segundo se incorporan muros de cortante ubicados estratégicamente en los marcos exteriores (sistema dual). Para las dos edificaciones se utilizan modelos estructurales complejos los cuales son sometidos a varios registros sísmicos del suelo blando con la finalidad de estimar y comparar la confiabilidad de ambos sistemas utilizando curvas de peligro de demanda. Es importante mencionar que también se hace una comparación de los resultados obtenidos del diseño de los dos sistemas estructurales en términos de otros indicadores de demanda ingenieril. El parámetro utilizado para estimar la confiabilidad estructural es la distorsión máxima de entrepiso, la cual se obtiene mediante análisis dinámicos incrementales que permiten la elaboración de curvas de fragilidad sísmica. La estimación de la confiabilidad estructural se hace mediante modelos probabilísticos al combinar las curvas de fragilidad y de peligro sísmico. Finalmente, con los resultados obtenidos se comprueba que utilizar el sistema dual puede ser una buena alternativa de diseño, obteniendo una solución más económica y un mejor comportamiento sísmico.

“…It can be said that shear walls ensure the structure's safety against earthquake loads and other lateral loads. If the primary retaining mechanism (or the only lateral load in a building) is in the wall, then the type of building is called a "shear wall structure" [9]. The use of shear walls can be essential from the economic perspective and the horizontal displacement control.…”

Shear walls' placement in specific positions could develop different structural responses to the building and affect the structure's strength to the received lateral loads. This research aims to find the variations in the shear walls' placement on the structure's response under the Direct Displacement Based Design (DDBD) method. The object of this research is the model of a 10-story reinforced concrete building located in Yogyakarta, Indonesia. Modelling of building structures is carried out in this study with four variations of shear wall placement. First, the walls are located at every building's corner. The shear wall is then positioned in the core of the building, where the apertures have shrunk. Then, the shear wall is located on the edge of the building. Last, the shear wall is located on the edge of the building. ANOVA method is used to analyze the significant difference, i.e., variations in the walls' placement. This research indicates the significant differences in the x-direction shear force and the y-direction moment The shear walls are suggested to be placed according to the building's condition and the earthquake ground site's class to produce an optimal structure to resist earthquake loads.
