Abstract

This experimental study aims to evaluate the compressive strength of concrete using palm kernel shells as a substitution for coarse aggregates. The utilization of locally available materials in abundance, such as palm kernel shells, can serve as a sustainable alternative in construction. This research is conducted to measure the influence of palm kernel shell usage on the mechanical properties of concrete, particularly its compressive strength. The research methodology involves the preparation of concrete mixtures with various levels of substitution of coarse aggregates with palm kernel shells. Test specimens were prepared with substitution percentages of 0%, 25%, and 60% with planned ages of 7 days, 21 days, and 28 days. Three cube specimens were cast for each planned age. The test results were used to compare the compressive strength of concrete with and without palm kernel shells and to evaluate the potential of palm kernel shells as a substitute for coarse aggregates in structural concrete applications. The research findings indicate that the highest compressive strength was obtained in the concrete without any palm kernel shell mixture (0%), measuring 379.86 kg/cm2. The highest compressive strength with the substitution of coarse aggregates using palm kernel shells was found in the 25% mixture, with a value of 362.57 kg/cm2, while the lowest percentage was recorded in the 60% mixture, with a value of 270.65 kg/cm2. Palm kernel shells have the potential to be used as a substitute for coarse aggregates in concrete. However, their utilization needs to be carefully analyzed and tailored to the specific conditions and requirements of construction projects. This research provides initial insights into the use of palm kernel shells in concrete and can serve as a foundation for further research in the development of environmentally friendly concrete using sustainable local raw materials

Abstract

The West Sumatra Regional Police Hall, initially designed as an open sports facility without a roof, is repurposed into a multifunctional center for sports activities, social events, and disaster emergency response. The existing structure, a portal frame of reinforced concrete columns and beams, requires strengthening due to budget constraints that prevent its demolition and reconstruction. This study aims to evaluate the structural performance of the building after retrofitting to accommodate additional loads, including a truss frame and roof coverings. The jacketing method is used for column retrofitting, involving an increase in cross-sectional dimensions and additional reinforcement to enhance the structure’s strength and stiffness. Structural analysis shows that the original building lacks adequate capacity to withstand internal and external loads. Post-retrofitting, the analysis demonstrates significant improvements, including reduced shear forces and bending moments in columns and beams, minimized inter-level deflections, and compliance with column interaction diagrams. These enhancements ensure the building is structurally safe, particularly against seismic hazards, and capable of fulfilling its new functions. The findings highlight the effectiveness of the jacketing method for retrofitting and its potential application in similar structural repurposing projects.

Abstract

Perencanaan bangunan tahan gempa ada dua cara yaitu, bangunan direncanakan berperilaku elastis saat terjadi gempa atau bangunan direncanakan berperilaku inelastis saat terjadi gempa. Salah satu usaha agar bangunan dapat tetap berdiri kokoh karena dampak gempa bumi adalah dengan menggunakan bracing konsentrik yang berfungsi sebagai penahan gaya lateral pada struktur dari suatu konstruksi. Penelitian ini bertujuan untuk menganalisis pengaruh penggunaan bracing dengan profil baja terhadap kinerja struktur beton bertulang pada bangunan bertingkat tiga dengan pemodelan A untuk bangunan tanpa bracing, model B dengan bracing inverted-V, dan model C dengan bracing cross. Berdasarkan hasil pengolahan data dan analisis data, didapatkan hasil bahwa gaya dalam terbesar terjadi pada bangunan tanpa menggunakan bracing, dan momen yang bekerja pada balok bangunan tanpa menggunakan bracing 57,536% lebih besar daripada yang menggunakan bracing tipe X (cross) dan 55,817% lebih besar dari pada bangunan menggunakan bracing Inverted-V. Kinerja struktur berdasarkan performance based design untuk bangunan menggunakan bracing dan bangunan tanpa menggunakan bracing yang dimodelkan, dikategorikan ke dalam level immediate occupancy karena nilai maksimum total drift yang didapatkan pada masing-masing bangunan lebih kecil dari 0,01 dan nilai maksimum total inelastic drift kecil dari 0,005

Abstract

In structural analysis, many calculations are encountered which are very complex, making it difficult to do with exact mathematical calculations. For easier analysis, numerical methods are needed to simplify the calculations. Complex building structures such as towers, multi-storey structures and other buildings, are idealized for simplification into a single degree of freedom system (SDOF), assuming that the dynamic response of structures due to earthquake loads is horizontal. The analysis of this model is correlated with numerical analysis, so it can be completed quickly. The numerical method used in this study is the 1/3 Simpson Integral Method, because this method is suitable for calculating dynamic structural responses such as structural displacement responses. The analysis procedure begins by entering the external forces on the structural system and calculating the resulting response value. The analysis can be repeated for a variety of different parameters, such as the mass of the structure, the dumping ratio and the stiffness of the structure. Structural response is calculated by sinusoidal dynamic load type for damped and undamped systems. The results of this study conclude that the relationship between the mass of the structure, the damping of the structure and the stiffness of the structure with the displacement of the structure has an inverse relationship, where with high mass, high damping and high stiffness, it can reduce the structure displacement.
