"ABSTRAKSambungan antara kolom dan balok merupakan bagian dari struktur bangunan yang sangat rawan terjadi kegagalan karena pada bagian ini terjadi transfer gaya antara keduanya serta bagian yang berperilaku sebagai penghubung disipasi energi antarelemen yang disambung. Konsep sambungan semi-rigid telah dikembangkan sejak dulu, beberapa model analitis sambungan semi-rigid balok kolom telah diteliti untuk memodelkan respons atas getaran pada sambungan balok kolom dengan mempertimbangkan perilaku nonlinear di zona sambungan untuk mengatasi dampak dari deformasi geser dalam analisis struktural. Analisis yang digunakan untuk mengetahui keadaan zona panel pada sambungan balok kolom ini menggunakan analisis fiber model, yakni bentuk pemodelan numerik yang digunakan untuk memprediksi hasil dari eksperimen terhadap struktur. Pada skripsi ini, analisis fiber model dilaksanakan secara numerik dengan menggunakan program komputer Drain-2DX Dynamic Response Analysis of Inelastic-2 Dimension dengan versi 1.10. Variasi nodal dan elemen, kurva kuat tekan beton, kurva tegangan-regangan baja, serta pullout dan gap diberikan dalam pemodelan untuk mengetahui parameter yang mempengaruhi kesemi-rigid-an sambungan balok dengan kolom.

ABSTRACTConnection between the column and the beam is a part of the building structure which is very prone to accure failure because in this section there is a transfer of force between both of them as well as the part that behaves as a liaison of energy dissipation among the connected elements. The semi rigid connection concept has been developed since a long time ago, several analytical models of semi rigid beam column connections have been investigated to model the response of vibrations on beam column joints by considering nonlinear behavior in the connection zone to overcome the impact of shear deformation in structural analysis. The analysis used to determine the state of the panel zone on this beam column connection is a fiber model analysis, which is a numerical assessment used to predict the results of experiments on the structure. In this undergraduate thesis, fiber model analysis is performed numerically using Drain 2DX Dynamic Response Analysis of Inelastic 2 Dimension computer program with version 1.10. Nodal and elemental variations, concrete compressive curves, steel stress strain curves, and pullouts and gaps are given in modeling to determine the parameters affecting the rigidity of the beam columns joints."

"Skripsi ini bertujuan untuk mengetahui persebaran temperatur pada beton massa yang ditinjau secara horizontal pada raft foundation Rasuna Tower. Parameter yang ditinjau dalam makalah ini adalah initial temperatur, temperatur maksimum, perbedaan temperatur dan tegangan yang terjadi pada beton massa secara horizontal. Batasan temperatur maksimum dan perbedaan temperatur yang diizinkan pada umumnya adalah 70°C dan perbedaan temperatur ≥ 20 °C. perbedaan temperatur yang terjadi tergantung dari pengendalian temperatur yang dilakukan. Temperatur puncak yang terjadi ± 80 °C. Temperatur puncak yang terjadi tergantung dari initial temperature dan mix design. Tegangan yang terjadi dipengaruhi oleh perubahan temperatur pada nodal. Semakin jauh jaraknya dari tepi maka semakin tinggi temperatur yang terjadi karena pelepasan panas yang semakin lama. Namun pada penyebaran tegangan, nilainya tidak dipengaruhi oleh jarak ke tepi beton. Tapi sangat dipengaruhi oleh lapisan insulasi dan terdekat dengan titik yang ditinjau.

This final report aims to determine the temperature distribution in mass concrete terms horizontally on a raft foundation Rasuna Tower. The parameters of interest in this paper is the initial temperature, maximum temperature, temperature difference and stress happened on mass concrete horizontally. The maximum temperature and the temperature difference that allowed in general is 70°C and not exceed 20°C. Temperature difference that occur depends on the temperature control is performed. Peak temperature occurred ± 80°C. Peak temperature is dependent on the initial temperature and mix design. Stress that occurs is influenced by changes in the nodal temperature. Increasing distance from the edge makes higher temperatures due to the longer heat release. The deployment stress is not influenced by the distance to the edge of the concrete but is strongly influenced by the insulation layer and the closest to the point of being reviewed."

"The response of concrete under tensile loading is crucial for most applications because concrete is much weaker in tension than in compression. Understanding the response mechanisms of concrete under tensile conditions is therefore key to understanding and using concrete in structural applications. Understanding the tensile properties of concrete summarises key recent research in this important subject.After an introduction to concrete, the book is divided into two parts: part one on static response and part two on dynamic response. Part one starts with a summary chapter on the most important parameters that affect the tensile response of concrete. Chapters show how multi scale modelling is used to relate concrete composition to tensile properties. Part two focuses on dynamic response and starts with an introduction to the different regimes of dynamic loading, ranging from the low frequency loading by wind or earthquakes up to the extreme dynamic conditions due to explosions and ballistic impacts. Following chapters review dynamic testing techniques and devices that deal with the various regimes of dynamic loading. Later chapters highlight the dynamic behaviour of concrete from different viewpoints, and the book ends with a chapter on practical examples of how detailed knowledge on tensile properties is used by engineers in structural applications."
