Study on Non-Engineered Building Vulnerability with Red Brick Masonry Wall through Finite Element Analysis

Abstract

In this study comparing two types of simple house forms that were built without using count analysis. The building uses beams and columns that are usually used in a simple house in Indonesia. The modeled building consists of a square cross section and L cross section, also the modeled wall consists of a full wall, a wall with door openings, walls with door and window openings. Modeling using STERA 3D software to model non-engineered building comprise beams and columns and STERA FEM software for modeling walls. Modeling was carried out to analyze building shear stiffness, earthquake acceleration, and wall deflection when receiving loads. The loading in this study uses dead loads and earthquake loads using the time history method. The results of the modeling are the largest shear stiffness of a simple house building with a square cross-section of 35 kN/cm. The maximum land acceleration resulting is 8.72 m/s2. The largest wall deflection occurs at a load of 20 kN with a deflection value of 58.83 mm on the wall with door and window openings. The high deflection value is caused by the influence of the width openings on the wall and the load go down to the wall.

Evaluation of Seismic Behavior Due to Vertical Irregularities in High Rise Reinforced Concrete Buildings

“…Saito (2016) melakukan penelitian mengenai respon bangunan bertingkat tinggi dengan periode gempa yang panjang menggunakan aplikasi STERA 3D menggunakan analisis time history. Selain itu beberapa penelitian ditemukan juga dengan menganalisis respon bangunan beton bertulang dengan aplikasi ini (Tanjung et al, 2019;Maulana et al, 2019;Zega et al, 2020). Dari seluruh penelitian tersebut menunjukkan bahwa aplikasi STERA 3D yang berasal dari Jepang ini cukup mampu untuk mengevaluasi penampilan bangunan beton bertulang dalam menahan beban gempa menggunakan metode analisis time history.…”
