Cortinas Atirantadas – CVA by Ricardo Oliveira on Prezi

Post Your ideas for ProZ. As prescribed in European Concrete Standard ENthe design service life for current structures is at least 50 years, which is applicable to reinforced concrete structures with anchored curtains. According to Lopesthe finite element method FEM is the most commonly used numerical method employed in geotechnical civil engineering due to its ease in dealing with heterogeneous, nonlinear nonlinear elasticity and plasticity and time dependent viscosity and densification problems.

Most proposed methodologies aim to define areas that are critical to landslides, that is, areas of greater susceptibility for the process to occur.

Reservation of rights to exclusive use No. It is a potential condition under which an accident could occur.

Figure 3 Schematic representation of the finite element analysis Tschiptschin, Hazards, however, represent the possibility or probability of some damage to a population people, physical structures, and production systems or to a segment of a population. The soil tends to settle over time, and the distributions of the grain particles and voids occupied by water are readjusted, which cause the material to consolidate and its resistance to increase.

Care must be observed with issues such as data entry, specification of soil and material parameters, spacing of the tie rods, and the distribution of the forces applied to the tie rods in this measurement. The objective of this research, which is related to the study of pathological manifestations due to the cracking processes of structures, is to analyze whether increasing loads on the tie rods of the anchored curtain containment structures behave as predicted by computational simulations when taking into account increases in informal properties uphill of those structures.

Auxiliary lines are used to simulate the excavation of the structure. Reviewing applications can be fun and only takes a few minutes.

The city of Rio de Janeiro is known worldwide for its natural beauty, which is mainly characterized by its particular geomorphology, i. Login or register free and only takes a few minutes to participate in this question. Cortias approximately 2, structures that have served as the primary solution for geological-geotechnical hazard mitigation in the city of Rio de Janeiro for 50 years since the creation of GEO-RIO require special maintenance attention and interventions to restore and extend their service lives.

Although NBR Testing of tie rods anchored to atiranadas ground specifies the procedures for verifying the performance of a tie rod using four tests basic, qualification, reception cortnas fluencythis test has the same nature as the previous tests, which is to place a load on the tie rod so that it presents a performance compatible with that determined by the design. Several concepts are used to address the landslide problem and its forms of investigation.

Peer comments on this answer and responses from the answerer agree.

This increase in multiple cracks will allow aggressive agents to enter the interiors of the reinforced concrete slabs when the structures are subject to aggressive environments, which can cause increases in pathological manifestations throughout their service lives.

They represent the parameters adopted by the GEO-RIO Foundation that are used in modeling specifications for the designs of the anchored curtains.

In stress-strain analyses involving soils, Safety Factors SFs can be obtained using soil resistance or workload parameters pertinent atirantaeas the problem under study. Initially, the analysis of the structural behaviors of the 20 anchored curtains executed in the city of Rio de Janeiro was developed considering the effects of the overload stresses due to the additional forces at the end of the project service life, which was estimated to be 50 years, as established in standard EN It can be seen that atirantaxas two lines that represent the tests simulated using clrtinas Plaxis computational system blue line and atorantadas load verification test red line do not meet for any of the 20 anchored curtains surveyed over five years during this research.

Over time, these anchored curtain hillside containment structures suffer increases in overload from the contained soil, which was not foreseen in the design, due to the increase in informal constructions in uphill areas with high geological-geotechnical risks and where most of the curtains in the scope of this analysis are located.

This indicator is useful to ensure minimum performance levels.

The calculation of the stiffness matrix, an interpolation function, allows relating the value of the variable of the problem to be solved in the nodes of each element with its geometry ckrtinas property, generating a system atirantadae equations in matrix form. Figure 7 Residual load verification testing underway. Another important consideration in the case analysis is that it is hard to obtain information regarding the informal properties located uphill from the anchored curtains or their residents, either due to high resident turnover or the construction dynamics of the houses.

The reinforcing bars of a hillside containment structure must absorb the tensile and compressive stresses arising primarily in the vertical parameters of the anchored curtains, which are dimensioned to resist not only bending but also the punching shear in the region of the tie rods. On the other atifantadas, the theoretical tests, i.

Over the years, the word has become synonymous with an abject housing reality. Residual load verification tests on anchored curtain tie rods must be performed every five years to obtain residual load values.
