Evaluasi Kinerja Direct-displacement Based Design Pada Perencanaan Bangunan Dengan Ketidakberaturan Tingkat Lunak

Saat ini banyak ditemui bangunan yang memiliki satu atau dua lantai yang tingginya lebihbesar dari lantai-lantai yang lainnya. Pada perencanaan ketahanan gempa, kondisi ini dapatmenghasilkan lantai yang lunak yang mengarah pada keruntuhan soft storey. Penelitian ini bertujuanuntuk mengetahui apakah adanya lantai lunak dapat mempengaruhi rumusan distribusi vertikal gayapada setiap lantai yang digunakan untuk bangunan beraturan, jika didesain dengan metode DirectDiscplacementBasedDesign(DDBD).Selanjutnya,penelitianinijugamengevaluasikinerjabangunanuntukmengetahui responnya terhadap gaya gempa. Sebagai studi kasus, dipilihlah bangunanperkantoran 8 lantai dengan denah tipikal di Surabaya dan Jayapura. Bangunan berupa sistem rangkabeton bertulang dengan lantai lunak di lantai dasar dan lantai 5. Struktur direncanakan menggunakanmetode DDBD pada target kinerja level-1 – no damage, level-2 – repairable damage dan level-3 – nocollapse, dan dianalisis kinerjanya menggunakan analisis non-linier dinamis riwayat waktu pada gempakecil, sedang dan besar. Hasil penelitian menunjukkan bahwa perencanaan DDBD paling aman adalahdesain dengan level-1 karena meskipun bangunan dengan sengaja didesain memiliki tingkat lunak,bangunan masih memiliki kinerja yang baik di semua level gempa, baik diukur dalam parameter driftratio, damage index, maupun mekanisme keruntuhannya. Untuk penelitian lebih lanjut dengan tinggilantai yang besar disarankan membuat kolom dengan kekakuan lateral diatas kriteria tingkat lunak(kolom yang lebih kaku), supaya tidak memiliki tingkat lunak

Quantum coherence as asymmetry from complex weak values

Quantum coherence as an asymmetry relative to a translation group generated by a Hermitian operator, is a necessary resource for the quantum parameter estimation. On the other hand, the sensitivity of the parameter estimation is known to be related to the imaginary part of the weak value of the Hermitian operator generating the unitary imprinting of the parameter being estimated. This naturally suggests a question if one can use the imaginary part of the weak value to characterize the coherence as asymmetry. In this work, we show that the average absolute imaginary part of the weak value of the generator of the translation group, maximized over all possible projective measurement bases, can be used to quantify the coherence as asymmetry relative to the translation group, satisfying certain desirable requirements. We argue that the quantifier of coherence so defined, called TC (translationally-covariant) w-coherence, can be obtained experimentally using a hybrid quantum-classical circuit via the estimation of weak value combined with a classical optimization procedure. We obtain upper bounds of the TC w-coherence in terms of the quantum standard deviation, quantum Fisher information, and the imaginary part of the Kirkwood-Dirac quasiprobability. We further obtain a lower bound and derive a relation between the TC w-coherences relative to two generators of translation group taking a form analogous to the Kennard-Weyl-Robertson uncertainty relation.Comment: 31 pages, no figure

Value of information-based risk and fatigue management for offshore structures

This paper proposes a framework for the planning of the structural integrity and risk management (SIRM) of offshore structures by utilizing the value of information and action (VoIA) analysis. Multiple structural health information sources, i.e. inspections, structural health monitoring (SHM) and damage detection systems (DDS), are modeled in dependency of the information acquirement state. In the probabilistic modeling, it is distinguished whether the information are predicted or already obtained. Two deteriorating structural system modeling approaches are illustrated and the pre-posterior and posterior updating of the structural system performance is formulated. To enhance the efficiency of the analysis of complex structural systems, a response surface method for load modeling is derived and the model uncertainty of the response surface is explicitly modeled. The formulated approaches are applied to a generic structural system and a typical deepwater jacket platform analyzing four SIRM scenarios. The optimal SIRM strategy is identified by maximizing the VoIA. The results show that the implementation of SIRM can reduce the failure risks and the expected total costs over the service life compared to a scenario without SIRM. It is also observed that information from SHM and DDS can reduce future inspection efforts and enhance the value of SIRM

Defining Social Sustainability and Socially Conscious Tourist in Sustainable Tourism Development

Sustainable Tourism Development (STD) consists of three dimensions known as environment, economic and social. Although these three dimensions influence each other and cannot stand on their own, and are assumed to be supportive to each other and compatible. However, most studies focus on the environmental and economic dimensions. The social dimension gains less attention and is difficult to attain and operationalize. In order to implement a balanced and successful STD, it needs to be supported by all the tourism stakeholder, including the tourist itself. Therefore, it is necessary to explore the social dimension of STDs and also tourist behavior regarding their social conscious. However, the discussions and understanding of social dimension in STD and socially conscious behavior are still limited. This study aims to define a clear understanding and definition of social dimension of STD which in this study is referred as social sustainability and also a socially conscious tourist. Starting with exploring the aspect of social dimensions formulation and exploring clear definitions of social dimensions of STD's and socially conscious tourist. This study is an exploratory study that aims to explore the boundaries of social dimension of STD and to develop a construct of socially responsible tourist. This study is a qualitative approaches, which includes systematic literature review and Delphi method to obtain expert judgment to gather social dimension aspects of sustainable development, especially in STD. The results of this study are social dimension's aspects of STD, an understanding of social sustainability and socially conscious tourist in STD

Oxygen reduction reaction mechanism on a phosporus-doped pyrolyzed graphitic Fe/N/C catalyst

The oxygen reduction reaction (ORR) mechanism on the active sites of a phosphorus-doped pyrolyzed Fe/N/C catalyst is examined by using density functional theory based calculations. The introduction of the phosphorus dopant creates three initial possible active sites for the ORR i.e., FeN4, C–N and P-doped sites. In the presence of O2, the P-doped sites become passivated while the rest of the catalyst sites are still functional. The ORR profile for the associative mechanism (the O2 molecule is reduced from its molecular form) on the FeN4 site is practically unaffected by the presence of the neighboring P[double bond, length as m-dash]O site. However, the ORR profile for the dissociative mechanism (the O2 molecule is reduced from its dissociated form) on the FeN4 site is significantly improved as compared to that on the undoped Fe/N/C catalyst system. This phenomenon is mainly induced by the distortion of C–C networks due to the presence of the neighboring FeN4 and P[double bond, length as m-dash]O sites, which leads to the stabilization of the *OH adsorption state on the C atoms next to the FeN4 site
