KOMPARASI KAPASITAS NOMINAL LENTUR PELAT KOMPOSIT BETON-DEK BAJA ANTARA METODE ULTIMIT, TEGANGAN KERJA, DAN SDI-ANSI 2017

Today, the most efficient slab construction method is the concrete-steel deck composite slab because there is no need to remove the deck after the concrete casting process. Nevertheless, reinforced concrete standard code (SNI 2847:2019) not emphasized a specific method to calculate the concrete-steel deck slab's nominal capacity. The code is embraced by the plastic method analysis, which is calculated the nominal capacity of the structure on the ultimate condition. However, several laboratory tests reveal a slip behavior between the concrete and steel deck before the slab reaches its ultimate condition. Therefore, alternative methods are needed to analyze the nominal capacity of concrete-steel deck slab. This study compares three different nominal capacity analysis methods to a laboratory test result. Those methods are ultimate, working stress, and SDI-ANSI (2017). The average error value of those three methods compared to laboratory test results in 35,57%, 9,48%, and -10,31% for ultimate, working stress, SDI-ANSI (2017) consecutively.it can be concluded the working stress method is the most accurate. However, SDI-ANSI (2017) is the conservative one, while the ultimate method is not recommended to analyze the concrete-steel deck slab's nominal capacity.

Thermal performance of exterior roof level amenity space in a cold climate - a quantitative guidance tool for landscape design

There are no known studies to quantify the effects of amenity space landscape structures located over habitable space as related to thermal performance. There are three main objectives for investigation in this MRP; Objective 1 – Thermal analysis of on-slab wall types, Objective 2 (O2) – Thermal analysis of example amenity space using results from O1, and Objective 3 (O3) – Recommended details that ‘work’ thermally and functionally. A quantitative methodology was utilized using 1D manual calculation (Glaser method) and 2D computer simulation (THERM) to study three CIP concrete wall conditions and variations which include; 1.0) base line condition, 2.0) modified condition, and 3.0) ultimate condition. Simulation results of O1 indicated that design of landscape walls could improve thermal performance by 55%, O2 found that there was an improvement of 60.5% between the worst and best performing conditions, and O3 recommended two wall variations to be utilized in landscape design which perform thermally and functionally.

Earth, Technology, Language: A Contribution to Holistic and Transcendental Revisions After the Artifactual Turn

The empirical turn, understood as a turn to the artifact in the work of Ihde, has been a fruitful one, which has rightly abandoned what Serres and Latour call “the empire of signs” of the postmoderns. However, this has unfortunately implied too little attention for language and its relation to technology. The same can be said about the social dimension of technology use, which is largely neglected in postphenomenology. This talk critically responds to Ihde (mainly) and Stiegler, and sketches a Wittgensteinian inroad to a more holistic and transcendental revision of postphenomenology which does not turn away from the artifact but places it in a wider social context and asks the question regarding the relation between language and technology. Finally, since the earth may be the ultimate condition of possibility, it is asked what this language-sensitive and transcendental approach may imply for rethinking our human position and agency in the Anthropocene. The paper ends with pointing to the role of language as transcendental condition that shapes the very project of thinking the “Anthropocene.”

« Connais-toi toi-même et tu connaîtras l'univers et les dieux », l’initiation dans Archaos ou le jardin étincelant de C. Rochefort

Archaos ou le jardin étincelant by Cristiane Rochefort, is a post-May 68 utopia. The learning process prescribed in this novel parodies/mocks traditional coming-of-age novels: rules are not enacted by an exogenous mentor. Classical intellectual guides are ridiculed. The process of initiation is turned inward, toward the self, and is accomplished by way of sex education, the ultimate condition for access to power. Resolutely feminist, this novel reconsiders the world led by women. Archaos is the story of a Dionysian journey under the guise of a political utopia which calls for symbolic death and for an esoteric renaissance under the auspices of the goddess Isthar.

Simulation Analysis on the Pressurizer Degassing Sub-System of Module Small Reactor (ACP100)

A pressurizer degassing sub-system is designed in Module Small Reactor (ACP100), which can be used to vent the non-condensable gas dissolved in Reactor Coolant during plant shutdown period by opening the remote degassing valve installed on top of the pressurizer. In order to verify the transient characteristic during the whole degassing process, a dedicated transient degassing program is developed based on the improved non-equilibrium multi-region model and the transient degassing model, which is used then to carry out a simulation analysis on this process. Also, the boundary condition models including pressurizer heater power model, pressure spray model, surge line flow model and critical flow model for degassing valve are established. The simulation results show that, under ultimate condition of hot-zero power operation, during the whole degassing process, the Pressurizer’s pressure drops to a maximum 0.038MPa, and the water level is raised 0.0637m above the normal level, which means, both of the pressure and water level are within the normal operation band and shall not initiate any safety signal. Meanwhile, the whole transient process lasts about 16 minutes, and then it enters into the stable degassing period. The gas concentration vs time curve is very smooth. It takes about 5.8 hours to remove the gas dissolved in Reactor Coolant from 35 ml(STP)/kg to 15 ml(STP)/kg. The analysis shows the Pressurizer Degassing Sub-system is safety, effectively and reliable.

Calculation of Lateral Soil Pressure at the Hydraulic Construction and its Sustainability on the Stone Bed

The engineering method of analysis of pressure of a ground on flat walls is offered at presence of combine strip superficial loading in view of seismic influences. It is recommended to determine a situation of an internal slip surface dividing an elastic zone from area of limiting balance, on the basis of the technical theory of the ultimate stress condition. Proceeding from a situation of an internal and external slip plane, size of strip loading on the fill, the pressure of a ground which is taking place in an ultimate condition, on an internal slip surface of is determined on developed by P. Yakovlev to the specified Coulomb's method [1], and on an internal side of a retaining structure on the basis of the Boussinesq decision. In comparison with the earlier developed way it is offered specified according to the Boussinesq theory a method of definition of pressure transmitted by bed on a ground of the basis and, as a consequence more reasonable definition of safety factor of stability of a structure. Thus, curvilinear normal pressure diagram in a ground under a sole of lay is replaced on isosides trapeziform.
