Abstract

This research is a continuation of a series of research on Tulungagung onyx waste. The large volume of onyx waste in the area around the Tulungagung onyx processing plant is used as a substitute for gravel aggregate in the concrete mixture which is processed into exposed concrete which has high aesthetic value. In this study, a finishing treatment process (panel thickness thinning) was carried out which aims to produce coarse aggregates from the walls of the onyx concrete waste panels as exposed concrete which has high aesthetic value. The researcher wanted to know the cracking behavior of the onyx concrete waste panel walls before and after the finishing process. The test object used is the test object of previous researchers, namely the wall of the onyx waste concrete panel size 80 cm x 40 cm x 6 cm with practical steel reinforcement Ø6 - 100 mm attached, so that in this study the researcher only carried out the finishing treatment of panel thickness thinning, in-plane three-point loading test and took data on the cracks that occurred. The result of the finishing process by grinding of 2 mm shows that the percentage of aggregate is seen on average 1.8% of the total surface area, while for the finishing of 4 mm it shows that the percentage of aggregate is seen on average 35%. No initial cracks were found on the surface of the specimen after grinding 2 mm or 4 mm. The cracks experienced after loading were flexural cracks, where all the samples had only one crack in the direction almost perpendicular to the panel axis. The bending stress that occurs in the panels during the initial cracking of the non-grinding panels, 2 mm grinding panels, 4 mm grinding panels is 4.75 MPa, 4.62 MPa, 4.60 MPa respectively.

Abstract

The most critical performance of a reinforced concrete composite structure is the binding behavior between its components. Optimal bond behavior is essential for guaranteeing the service performance of reinforced concrete structures, influencing the structure's performance throughout its life cycle. In practical structural analysis, it is commonly accepted that the two do not generate relative slippage, leading to discrepancies between the studied structure and the real engineering conditions. Currently, numerous scholars worldwide have employed diverse testing methodologies, thoroughly examining various aspects influencing the binding behavior between bent rebar and concrete, resulting in numerous results. This paper provides a comprehensive review of the research status regarding the bonding performance of reinforced concrete, grounded in the pertinent findings of various scholars. It examines the bond mechanism, the experimental methodologies for assessing bond behavior, and the factors influencing this behavior. It is anticipated that it will serve as a reference for scholars examining the bond behavior of reinforced concrete in the future.

Abstract

Abstract The use of base isolation as an earthquake mitigation technology is an innovative solution in designing earthquake-resistant building foundations, especially in areas with high seismic activity. This study aims to analyze the performance of base separation in damping earthquake forces received by the upper structure. Literature studies were conducted by referring to various previous studies showing that this technology can dampen the structural response to ground vibrations, extend the vibration period, and increase the overall stability of the building. The analysis was carried out by modeling the base separation system using simulation software to study its effect on base shear forces and structural cooling. The simulation results show that base separation can dampen base shear forces by up to 58% compared to conventional structures without isolation. This technology also shows advantages in maintaining structural integrity during major earthquakes. These findings are expected to be a reference for building design to improve the safety and resilience of building structures in earthquake-prone areas. Keywords: base isolation, earthquake mitigation, foundation design, base shear force, earthquake resistant building Abstrak Pemanfaatan base isolation sebagai teknologi mitigasi gempa bumi menjadi solusi inovatif dalam perancangan pondasi bangunan tahan gempa, terutama pada daerah dengan aktivitas seismik tinggi. Penelitian ini bertujuan untuk menganalisis kinerja base isolation dalam meredam gaya gempa yang diterima oleh struktur atas. Studi literatur dilakukan dengan mengacu pada berbagai penelitian terdahulu yang menunjukkan bahwa teknologi ini dapat meredam respon struktur terhadap getaran tanah, memperpanjang periode getaran, dan meningkatkan stabilitas bangunan secara keseluruhan. Analisis dilakukan dengan memodelkan sistem base isolation menggunakan perangkat lunak simulasi untuk mempelajari pengaruhnya terhadap gaya geser dasar dan deformasi struktur. Hasil simulasi menunjukkan bahwa base separation mampu meredam gaya geser dasar hingga 58% dibandingkan dengan struktur konvensional tanpa isolasi. Teknologi ini juga menunjukkan keunggulan dalam menjaga keutuhan struktur saat terjadi gempa besar. Temuan ini diharapkan dapat menjadi acuan bagi perancang bangunan untuk meningkatkan keamanan dan ketahanan struktur bangunan di daerah rawan gempa. Kata kunci: base isolation, mitigasi gempa, desain pondasi, gaya geser dasar, bangunan tahan gempa

Abstract

Penelitian ini menyajikan pendekatan konseptual dan eksperimental dalam memodelkan jaringan saraf tiruan (neural network) sebagai suatu transformasi nonlinier berlapis antar ruang vektor berdimensi tinggi. Dengan mendasarkan pada kerangka matematis komposisi fungsi linier dan aktivasi nonlinier, studi ini memetakan bagaimana representasi data secara spasial berubah melalui setiap lapisan jaringan. Menggunakan data sintetis berdimensi tinggi dan arsitektur multilayer perceptron (MLP), transformasi internal jaringan dianalisis baik secara visual melalui proyeksi PCA dan t-SNE, maupun secara kuantitatif melalui pengukuran perubahan metrik spasial. Hasil eksperimen menunjukkan bahwa jaringan saraf tidak hanya berfungsi sebagai aproksimator fungsi, tetapi juga secara aktif membentuk ulang geometri manifold data untuk meningkatkan keterpisahan antar kelas. Fungsi aktivasi seperti ReLU dan tanh terbukti memiliki dampak signifikan terhadap struktur representasi, dengan ReLU menghasilkan sparsifikasi spasial yang lebih kuat. Temuan ini mendemonstrasikan bahwa pemahaman terhadap dinamika spasial dalam neural network dapat memberikan fondasi yang lebih transparan dalam interpretasi model, serta membuka arah baru dalam riset interpretabilitas deep learning berbasis pendekatan matematis dan geometris.
