Um planejamento ortogonal guliveriano: uma leitura modular da Túrio do período clássico

This paper uses the Gulliverian metaphor to examine the organization of a well-known Classical orthogonal planning in Magna Graecia, south Italy. After observing the relationship between the elements of the urban grid of Thourioi, we will propose the application of a modular unit formed by the sum of ten Attic feet by the geometer of its urban plan. According to our main argument here, this module orientated the land-measurement of Thourioi by co-measuring the width of ithe roadway network and width/length of blocks, lots, and “major rectangles”. Furthermore, certain alignments in its planning are physically established, as it will be demonstrated in the case of its major roads. Thourioi calls forth through its compositional structure of older formulas a wider horizon of orthogonal planning tradition, an ancient scansion rhythm reified in archaeological patterns of many Greek Western foundations since the VIII century BC.

PROFESSIONAL TRAINING OF SECURITY GUARDS ON THE BASIS OF SYSTEM MODULAR PROJECT OF OBJECT PROTECTION

The article deals with the problematic issues of professional training of law enforcement officers who would be able to ensure reliable protection of objects and security of individuals. The analysis of security guards’ professional requirements and features of their official activity has been carried out. The method of training of security guards has been developed on the basis of systematization of knowledge, skills taking into account various modules, modular blocks in a single complex that gives the chance to the future security guard to master knowledge consistently and to provide the whole process algorithmization. On the basis of the created technique the model of security guards’ training is developed in general. The main training modules and their modular blocks are: acquisition of knowledge on the main areas of ensuring the overall organization of objects protection, which minimizes and eliminates the impact of other threats that may interfere with the normal functioning of the object; ability to provide a description of the object by external and internal characteristics; possession of a modern set of engineering and technical means of protection, including: fire-fighting modular unit, infrastructure unit, alarm system protection unit, access control and management systems, reliable modular unit, etc. The main stage of law enforcement personnel training is a formation of abilities to use protective modules in the conditions of external and internal interventions, threats etc. Actions of unauthorized entry on the object have been defined. A method of detecting factual intrusion (attempt) into the area of the protected object is provided. Examples of psychotic behavior of the offender are considered in the training process. The table shows the potential ability of the offender to act depending on the motivation level of emotional preparedness that correlates with his/her actions. The positive influence of the proposed innovations on the level of theoretical and practical training of future security guards has been revealed. The experiment confirmed the effectiveness of security guards training method based on the modular design system of object protection.

The article describes operation principle and design of a mobile modular unit for electrochemical decontamination of metal surfaces. It presents the experimental data on its testing which involved various real-world radioactively contaminated objects with corrosion products and layers of mechanical contamination present on their surfaces. The unit can be used to decontaminate large-size metal equipment of radiochemical plants (hot cells, glove boxes) without fragmentation, in semi-automatic mode with a minimum exposure time of personnel in the work area.

Study on the Seismic Performance of Box-Plate Steel Structure with Openings Modular Unit

The box-plate steel structure residence is a box structure with stiffened steel plates directly used as load-bearing walls and floors. In practical engineering, due to the functional requirements of the building, it is necessary to open door or window openings on the box-plate steel structure walls. To study the seismic performance of the box-plate steel structure with openings system, two three-story single-compartment box-plate steel structures with openings modular units were designed and fabricated according to the 1:3 reduced scale. Through the quasi-static loading test, numerical simulation, and theoretical analysis, the failure process, failure mode, lateral force resistant capacity, and hysteresis performance of the specimens were studied. The impact of the different opening areas and opening position on the seismic performance of the box-plate steel structure was emphatically analyzed. The results of the test indicated that the openings on the steel wall plate would reduce the initial stiffness and the lateral force resistant capacity of the specimen; the destruction of the box-plate steel structure with openings modular unit under the low cyclic loading effect started with the tear in the corner of the openings and ended with the tear in the corner steel wall plate. Then, the finite element analysis (FEA) models were developed to supplement the experimental study, and the comparisons were made between measured and simulated results on load versus displacement relationships and failure modes. On the basis of the stressing mechanism of the box-plate structure modular unit, the calculation equation of the lateral force resistant capacity of the box-plate structure with openings modular unit was put forward. Then, the proved finite element analysis (FEA) models were used for parameter analysis of different influence parameters to verify the proposed calculation equation. The results showed that the proposed calculation equation had high accuracy and could be used as a design basis for practical engineering.

Study on the Seismic Performance of Box-Plate Steel Structure Modular Unit

To study the seismic performance of the box-plate steel structure system, two three-storey single box-plate steel structure space stress-bearing unit test pieces have been designed and fabricated according to the 1 : 3 reduced scale. In addition, the quasi-static loading test has been performed on the test pieces where the destruction process, destroy mode, bearing capacity, hysteretic behavior, etc., have been studied and the impact of reinforcing measures with a corner or not on the seismic performance of test pieces has been mainly analyzed. The test results show that the destruction of the box-plate steel structure modular unit under the low cyclic loading effect starts with corner buckling and ends with corner wallboard tear. The test piece has excellent bearing capacity and energy dissipation; the corner reinforcing structure measure also has enhanced the seismic performance of the modular unit. Based on the test, we have taken finite element numerical simulation to the test pieces, compared the analysis result of the test with the finite element, and verified the effectiveness of the finite element analysis method. This paper designs four groups of 64 finite element model test pieces and discusses the influence law of the height-thickness ratio of the wallboard, flexibility coefficient of corner reinforcing structure rib, and axial compression ratio to the seismic performance of the modular unit. The results show that the bearing capacity of the test piece is decreased with the increase of axial compression ratio under the premise that the wallboard height-thickness ratio and flexibility coefficient of the corner reinforcing structure rib are certain. Based on the above analysis results, we have put forward the lateral force resistance calculation model of the reinforcing structure modular unit with or without corner.
