Construction Loads

The main structure of a performing arts center is in a bowl shape, formed by cantilever frames. When constructing, a temporary steel support system is designed to withstand the construction loads. The structural support system which is 30 meters high, is divided into five layers. In order to ensure the overall stability of the steel frame, scissors are set every three cross along the ring to the medial and lateral column. Since the loads are very big, bearing capacity and stability analysis of the support system are carried out. According to the site construction schedule, the loading processing is divided into 4 working conditions. Under each load condition, static and linear buckling analysis is conducted. For economic consideration, member sizes are optimized by pursuing the similar stress ratio based on the results of static and linear buckling. Structural software SAP2000 is employed as the analysis software. The results showed that: the working conditions 4 is the most dangerous working condition. The main stresses of beams and columns on the axis position are larger than other positions. The bucking analysis indicates that working conditions 1 to 4 the buckling factors of first-order buckling modes are greater than 1.0 under working conditions 1 to 4, which explaining that under the current loads, the steel support system is reached the required overall stability.

Appraisal of dam slope safety is essential for security and stability of the dyke that has been constructed for many years. According to the requirements of the appraisal of dam safety, the stability analysis of slope of Shegang dyke has been carried out by using Sweden circular-arc method, Bishop method, Engineer Corps method and Lowe method four methods under many kinds of working conditions and some conditions when the saturation line raising. Combined with the design code form embankment dam, the calculation results can be analyzed. The analysis can show that the security indexes of anti-slide under four kinds of working conditions and some conditions when the saturation line raising meet the requirements of the design code. This can provide basis for the reinforcement design of the dam, which also has a certain directive significance for the safe operation and observation of the dam in the future.

The Stability

Abstract A decision support system with damage stability analysis has been recognized as an important tool for passenger ships. Various software applications have been developed and taken into use over the years, without a direct link to any compelling requirement, set forth in the international regulatory framework. After the Costa Concordia accident, new regulations have been established, setting minimum requirements for a decision support system, as an extension to a loading computer. Yet, more advanced systems have been developed recently, aiming at providing valuable additional information on the predicted development of the stability of the damaged ship. This paper presents these alternative decision support systems with damage stability analysis methods for flooding emergencies on passenger ships. The technical background, usability, and usefulness of the various approaches are compared and discussed, taking into account the important statutory approval point of view. In addition, practical examples, including past accidents, are presented and discussed.

Waste Pickers

This study presents information collected from waste pickers in the southern, south-eastern and north-eastern regions of Brazil to guide the development of a collection vehicle and a support system for the definition of collecting routes. The study had three objectives: to specify the profile of waste pickers of recyclable materials in the three surveyed regions; to diagnose the working conditions of individuals linked to associations and cooperatives of waste pickers and to identify the physical and operational structure of the waste picker organizations. To reach these objectives questionnaires were issued to waste pickers linked to associations and cooperatives that collect recyclables using human- or animal-powered vehicles and to the waste picker organizations themselves. Based on the results of this study, we are able to provide the requirements for the development of the collection vehicle, to draw a profile of the waste pickers in the three study regions and have better understanding of the working and physical conditions and the organizational structure of waste picker entities. It can be concluded that waste pickers suffer several forms of deprivation, resulting in the marginalization, prejudice and exclusion of individuals who conduct this work, making it essential to promote actions that contribute to the social inclusion of waste pickers in their productive segment.

The Stability

On the construction of green open space Jl. Kinibalu Banjarbaru There is a 6 meters tall slope beneath which the river is lined up during the rainy season and makes the slope exposed by water plus the absence of load or traffic on it make the pore figures on the land is large. Therefore, for protection reason, there is a soil alignment in the construction of soil retaining walls. The planned ground retaining wall type is cantilever and gabion. The stability analysis of the ground retaining walls is done manually and with the help of the Geoslope/W 2018 software. The value of the stability of the style against the bolsters, sliding, and carrying capacity of the soil using manual calculations for cantilever type and Netlon qualifies SNI 8460:2017. And for the overall stability calculation using Geoslope/W 2018 software obtained safety factor (SF) > 1.5. From the analysis, the design of planning can be used because it is safe against the dangers of avalanche.
