A study on the structural performance of the tensioning air beam system (TABS) is presented. TABS consists of the air beam, steel frames and cable struts and is a hybrid structural system. This system has the advantage of reduced self-weight and is easy to construct while it can improve the load bearing capacity of membrane structures. It maximizes the structural capacities of individual elements, thus can be considered as a very effective system in both structural and economical aspects. In this study, a structural test was carried out to investigate the structural performance of TABS under different membrane pressure conditions. A simple analytical model was proposed to predict the structural behavior of TABS and its validity was evaluated by comparing its results with the test values.

Performance-Based Plastic Design (PBPD) is a structural analysis that can be used to review structural performance. This method is increasingly popular to be used in the earthquake-prone area. This method is based on energy method that can be applied to steel or concrete structures. Meanwhile, Indonesia has already SNI 1726:2102 to be used as a guide in designing the thrust load to review the level of structural performance. Both of these things need to be used as a reference in areas that were initially considered safe from the earthquake but based on the development of earthquake micro zonation maps, it is very possible to become potential areas that also become earthquake regions. For this reason, the case of the structure that was built in the Pekanbaru area was taken. From the analyses of structural behavior, the structure that applied PBPD has greater displacement than the structures that apply the thrust load of SNI 1726: 2012. The percentage of displacement that occurred was 8-37 %. Based on performance analysis, the structures according to PBPD shows a better level of performance to the application of SNI 1726: 2012 thrust load.

Geometric Morphology

Deployable structures can provide a change in the geometric morphology of the envelope by contributing to making it adaptable to changing external climate factors, in order to improve the indoor climate performance of the building. They have the ability to transform themselves from a small, closed or stowed configuration to a much larger, open or deployed configuration being also known as erectable, expandable, extendible, developable or unfurlable structures. According to their structural system, deployable structures can be devided in four main groups: spatial bar structures consisting of hinged bars, foldable plate structures consisting of hinged plates, strut-cable (tensegrity) structures and membrane structures. In this paper a short review only on two of these groups of deployable structures for arhitectural applications will be presented.

AbstractRecently, as a new precast concrete (PC) construction method for increasing economy and constructability, the PC double-beam system has been developed for factories or logistic centers, where construction duration is particularly important. In this study, half-scaled PC double beam–column connection was tested under gravity loading and cyclic lateral loading. The major test parameters included the use of the spliced PC column and the addition of reinforcement at the beam–column joint. In the gravity loading test, the flexural behavior of the PC double beam was investigated. The test results showed satisfactory flexural capacity at the PC double-beam section, validating the composite action between the PC and RC members. In the cyclic lateral loading test, the seismic performance of the PC double beam–column connection was investigated. Based on the test results, the failure mode, load-carrying capacity, deformation capacity, energy dissipation capacity, secant stiffness, and shear strength of the PC double-beam system were evaluated and compared with those of a conventional RC double beam–column connection. According to the test results, the structural performance of the PC double beam–column connection was comparable to that of the RC double beam–column connection and satisfied the acceptance criteria of moment frame in the ACI 374.1-05 provision.

Negative Gaussian Curvature

Tensile structures are currently the most advanced lightweight structures. Apart from their very small self-weight, they are also characterized by a double curved form with a negative Gaussian curvature. In addition, this is one of the most recent structural systems to be designed and because of that a lot of research work is still being done on its improvement. This paper will give a brief overview of the development of tensile structures. Their most modern sub-type, membrane structures, was analyzed in more detail. The characteristics of this system, its loading and the structural material it is made of were also studied. Special attention is paid to the form of this structural system. In the end an overview of the most significant objects constructed using the tensile structure system is offered, including the Olympic stadium in Munich as an example of cable net subsystem, and the roof of the central court in Wimbledon and the stadium in Durban as representatives of the membrane subsystem. In addition to the significant advantages of this system, the drawbacks are also highlighted.

The Carajás railway is operated by Vale SA and is used to transport the Brazilian production of iron ore mine located in the state of Pará until Itaqui harbor in Maranhão state. With 892 km in length, the railway will be doubled due to the prospect of increased production, which requires verification of the structures of bridges to ensure safety under loading up to 23% larger. The railway bridge in reinforced concrete has five hyperstatic spans with 25 m long and was built over Sororó river in the southeast of Pará. To better evaluate its structural performance under current loadings, several structural elements were monitored with strain gages and the concrete was characterized by non-destructive and destructive testing on the structure. This information was used in a computer model to estimate the future structural behavior. The methodology was satisfactory as the estimated structural performance for future loadings, meeting the recommendations of the Brazilian technical standards.

Pipeline systems for deepwater applications must be designed to withstand operational loads and to give adequate thermal insulation to the hydrocarbon being transported. Sandwich pipelines composed by inner and outer steel pipes and either cement or polypropylene as core material are proposed here as viable alternatives to currently used pipe-in-pipe systems. The main advantage of these sandwich structures is that the core material and geometry can be selected so to provide both thermal insulation and good structural performance in conjunction with inner and outer pipes. In this paper, the structural behavior of such sandwich pipes under external pressure is studied through a series of small scale experiments and nonlinear numerical analyses based on the finite-element method.

Corrosion of reinforcement can significantly affect the bond strength between the steel bar and the surrounding concrete thus greatly reducing the load bearing capacity of the concrete structure. In this paper, a simple analytical model is proposed to evaluate the maximum bond strength of corroded concrete with varying rebar diameters and concrete cover thickness. Predicted results compared well with experimental test data.
