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.

ANSYS14.0 structural analysis software is used in order to make a ring rib-reticulated shell for the overall stability analysis. Considering the geometric nonlinear analysis and initial geometric imperfections influence , obtain a key node of the load - displacement curve and assess the ultimate strength of the structure. The results showed that: the structure meets the "Space grid rules" for monolayer shells stability requirements. And it is found that load distribution form and initial geometry defect has a great deal whit bearing capacity of single-layer lattice shell stability by comparison.

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.

Abstract The overall stability of the Rovinari dry ash slurry impoundment is analyzed using a coupled seepage-stability analysis with the Finite Element Method in a bidimensional model. To better understand the behavior of such a complex structure, based on the material properties presented in Table 2, the hypotheses presented in Table 4 and described as such, a number of 9 general hypotheses were analyzed, at 178.00 m a.s.l. deposit elevation and final designed height of approximately 35.30 m which corresponds to 191.3 m a.s.l.. The results are presented in tabular form, only 8 diagrams are selected which show the Factor of Safety for hypothesis 0 and 3 which are considered to best describe the real-life conditions regarding the boundary conditions used. The results show that even at maximum designed height, the deposit is stable in the most realistic worst-case hypothesis 3, with a Factor of Safety of 1.177.

Loading Case

Folded plate structure with flat truss is applied in the roof steel structure of the natatorium in Huai’an sports center. In this paper, mechanical analysis on loading case and dynamic characteristics of the roof steel structure is accomplished. Overall stability analysis is also completed by FEM software STRAND7. Analysis results indicate the scheme is in accordance with safety and aesthetic is appropriately designed, which could figure out that bearing capacity and seismic performance of the folded plate structure are satisfactory.
