Abstract:
To evaluate the ductility and energy dissipation capacity of the beam with concrete-encased steel truss, eight specimens with different types of steel truss, reinforcement ratios, and shear span ratios were tested by low-cyclic loading regime. The results indicated that beams with concrete-encased steel truss performed plumped load–displacement hysteretic loops as well as high strength and stiffness. Moreover, cross-web members improved their seismic behavior more effectively than non-cross-web members. Finally, the restoring force model of concrete-encased steel truss beam is proposed in accordance with the experimental results, which can be used to predict the load–displacement behavior of concrete-encased steel truss beam. The results could also provide a reference for the design and application of concrete-encased steel truss beam in practice.

Abstract:
Based on existing experimental results, the finite element analyses were carried out on shear wall structures with steel truss coupling beams. This work studied the seismic behaviors and the working mechanism of the steel truss coupling beam at the ultimate state and put forward two parameters: the area ratio of web member to chord and the stiffness ratio of coupling beam to shear wall. The seismic optimum design method of the coupling beam was also proposed. Afterwards, a comparative analysis was implemented on the three-dimensional shear wall model with steel truss coupling beams designed by the proposed design method. The results show that the structures designed by the proposed method have excellent seismic behaviors, the steel truss coupling beams have enough stiffness to connect shear walls effectively, and its web members have appropriate cross sections to dissipate seismic energy.

Abstract:
As for structural beam of travelling bridge under reciprocate loads, at the bearing there will be a large change in stress of structure, while at the ends and midspan, the change of stress of structure will be simple. In this paper, based on the bearing features of travelling bridge structure, as well as features of steel-truss beam and steel box beam, a new composite structure, which is named as steel truss-steel truss box beam, is put forward. This new structure adopts steel box beam with truss inside at the bearings, and adopts steel truss beam at the midspan. Based on a certain engineering project, combined with ANSYS, according to a serious of sizes and structure styles, work of modeling, analysing and optimizing has been done in this paper. As calculating results showed, steel truss-steel truss box beam not only has higher bearing capacity, structural bearing capacity and a better wholeness, but also has a lower steel usage, which can provide references for similar composite structures' research in future.

Abstract:
Steel truss coupling beam is a new type of steel coupling beam structure. To investigate seismic behavior of this coupling beam, low cyclic loading tests for four full-scale specimens of steel truss coupling beam are presented. The specimens are designed considering three factors which are T-stub steel, angle steel and material strength. The experimental data show that steel truss coupling beam has good ductility, and can consume a great quantity of earthquake energy. By enlarging the sections of cross abdominal trusses and chord members, bearing capacity and stiffness of the whole coupling beam are greatly increased.

Abstract:
Coupled wall systems are often used in high-rise buildings in zone of high seismic risk to provide lateral resistance to earthquake loading. Once damaged, reinforced concrete coupling beams are costly and time-consuming to repair post-earthquake. To enhance the seismic resilience for coupled wall structures, a novel replaceable steel truss coupling beam is first introduced. The proposed replaceable steel truss coupling beam consists of chord members at the top and bottom, respectively, and two buckling-restrained energy dissipaters are employed in the diagonal direction. The energy dissipaters can yield first before the wall piers and dissipate large amounts of energy to protect the main structure under seismic loadings. In addition, the energy dissipaters can be easily installed and post-earthquake repaired through pin connection with the chord members. This article mainly focused on the numerical and theoretical analyses of the proposed replaceable steel truss coupling beam, and nonlinear analytical models were developed in PERFORM-3D. An 11-story prototype structure was designed per Chinese code. The seismic response of hybrid coupled wall system with replaceable steel truss coupling beams was evaluated using nonlinear time history analysis and compared with the response of reinforced concrete coupled wall system with reinforced concrete coupling beams under seismic loadings. Results show that the proposed replaceable steel truss coupling beam leads to a good seismic response with reduced interstory drifts of the systems and rotational demand in the beams and wall piers due to a large energy dissipation capacity and overstrength.

The analysis to the staged construction of the long span steel transfer truss was performed. The focus was on the stress and deformation analysis of the transfer truss, the interactions of the transfer member with the concrete tube, and the combination analysis of the steel girder and concrete beam. It was proved that the method of staged construction can get the good result that can make full use of the characteristic of the steel material, make steel truss bear more load effect in the construction stage. So the load to the concrete tube is lessened, which makes the load effect of the structure is more rational. Some advices for the construction and design of steel transfer truss is also provided.

Abstract:
An optimizing design idea is produced for the structure of top beam of electrostatic precipitator casing. The thermos cabinet and the original box shaped top beam of casing compose a truss beam system whose overall section height is increased greatly, resultantly, the bend bearing capacity of truss beam increases significantly than that of the original top beam of casing. Consequently, the wall thickness of box section of the original top beam can be reduced so that the steel consumption can be saved. Based on a practical project, the load effects on truss beam were investigated, respectively, including the air pressure difference and the temperature difference among external layer, thermos cabinet and interior of casing. Besides, the evaluation method of internal force in truss beam was investigated and the selective preference of truss beam configuration was conducted. The unfavorable load cases of air pressure difference and temperature difference are proposed for truss beam design. Besides, the accurate evaluation method of internal force and the design method for economical configuration of truss are proposed. In consideration of load bearing effect of thermos cabinet layer, the optimized design of truss beam originating from box sectioned top beam can ensure the truss works safely and reduce the steel consumption significantly.

Abstract:
<p>A cable-stayed bridge, whose main span is 230 m, is a four-line railway steel truss bridge. It is the first time to use only two main trusses in four-line railway truss bridge. In order to solve the transfer problem of wide truss-deck system and the design of the horizontal deck-beam, auxiliary longitudinal beams and horizontal K-bars are installed near lower chords of main truss. This is an innovative deck system, and we need to research on the structure performance. In this paper, the comparative analysis between the new type of deck system with horizontal K-bars and the traditional deck system with multi-crossbeam were carried out by FEM which focus on the deck structural characteristics, system stiffness, local deformation, etc. Also, in order to carry out the model test, a scale segmental experimental model of deck structure with horizontal K-bars was designed and manufactured. The FEM results show that: the bridge deck system with horizontal K- shaped braces is better than the multi-crossbeam deck system in structural stiffness, local deformation, participating rate of longitudinal force. And, the experimental results were in good agreement with the results of FEM analysis, which verified the correctness of FEM results and the rationality of design. The working condition of the bridge is good since opened on December 26, 2014.</p>

Abstract:
<p>The main entrance of Chongqing West Railway Station adopts the non-landing compound arch with a span of 108m. In this paper, the nonlinear finite element theory is applied to analyze the bearing capacity and seismic ductility of the compound arch joints. Low frequency cyclic loading tests are performed on the 1/5 scale model. Based on the calculation and test results, a double beam structure and a section of steel truss are placed in the arch joints to bear the force of the arch. Moreover, the buckling-restrained brace (BRB) is placed in the lower part of the arch that enables most force directly transmit to the foundation of the arch. Unlike BRB’s common use as an inter-column support, it now acts as a buckling constraint support in the large earthquake. For instance, it can be yielded before the frame column to improve earthquake resistance. The research results indicate that the compound arch joint structure successfully accomplishes the seismic design goals of strong joints with weak component. Moreover, the study provides the theoretical basis and design reference for the application of BRB and long-span arch structures in high-speed railway station.</p>

<p>Paudèze bridges are two 400‐m long parallel highway bridges located in Switzerland and opened to traffic in 1974. After over 40 years of service life, both bridges must be completely rehabilitated and strengthened while constantly maintaining 2 traffic lanes in both directions.</p><p>The bridge deck slab was strengthened using UHPFRC (Ultra‐High Performance Fiber Reinforced Concrete) struts. These inclined struts connect the end of the deck slab cantilever and the box girder web, forming a Warren truss. They thus reduce the bending moments in the deck slab and the existing steel reinforcement could be kept.</p><p>The joint between the prefabricated UHPFRC struts and the existing concrete web is done through a cast in‐ place UHPFRC beam, without any mechanical connection. Forces go through the joint and into the web by a combination of friction and compression forces.</p><p>Various experimental tests and numerical simulations confirmed the feasibility of this solution. In particular, the UHPFRC‐concrete web connection, the UHPFRC‐UHPFRC connection and the global behavior of the strut were tested and modelled.</p><p>The strengthening of the bridges decks took place between 2017 and 2019. The developed solution, using UHPFRC struts, was shown to be very effective to strengthen the deck and creates a rhythm in the structure.</p>

<p>The El Salvador Project is a student-led initiative born in 2001 at Imperial College London that provides simple and effective engineering solutions to rural communities in El Salvador. The projects are developed in close collaboration with the Salvadorian NGO REDES and the UK-based charity Engage for Development. This paper presents the work developed over the summer 2019, when a footbridge was constructed for the School of the community of El Yomo, in the town of Alegría. The footbridge was intended to restore the path connecting the main settlement with the local school, which heavy rainfall had eroded in the previous years forming an impassable ravine. The footbridge was designed as a 15 m long steel truss beam supported on masonry walls. The construction was a collective effort. The main challenges faced during construction were the unexpected conditions of the site, the unreliable supply of materials and the lack of means for excavation, lifting and auxiliary constructions. The success of the project relied considerably on the knowledge of the local workers. The involvement of the community helped develop a feeling of ownership over the project which has resulted in a strong commitment in its maintenance since the opening. The footbridge was enthusiastically inaugurated by the community and has provided the children of El Yomo with a safer and faster route to their school, based on a comprehensive risk management approach.</p>

In recent years, there has been a growing demand for high-power-density direct-drive generators in the wind industry owing to their high reliability, torque per unit volume, and conversion efficiencies. However, direct-drive wind turbine generators are very large, low-speed electric machines, which pose remarkable design and manufacturing issues that challenge their upscaling potential and cost of implementation. With air-gap tolerance as the main design driver, the need for high stiffness shifts the focus toward support-structure design that forms a significant portion of the generator’s total mass. Existing manufacturing processes allow the use of segmented-steel-weldment disk or spoke-arm assemblies that yield stiffer structures per unit mass but tend to be heavier and more expensive to build. As a result, there is a need for a transformative approach to realize lightweight designs that can also facilitate series production at competitive costs. Inspired by recent developments in metal additive manufacturing (AM), we explore a new freedom in the structural design space with a high potential for weight savings in direct-drive generators. This includes the feasibility of using nonconventional complex geometries, such as lattice-based structures as structurally efficient options. Powder-binder jetting of a sand-cast mold was identified as the most feasible AM technology to produce large-scale generator rotor structures with complex geometry. A parametric optimization study was performed and optimized results within deformation and mass constraints were found for each design. The response to the maximum Maxwell stress due to unbalanced magnetic pull was also explored for each design. Further, a topology optimization was applied for each parameter-optimized design to validate results and provide insights into further mass reduction. These novel designs catered for AM are compared in both deflection and mass to conventional rotor designs using NREL’s systems engineering design tool, GeneratorSE. The optimized lattice design with a U-beam truss resulted in a 24% reduction in structural mass of the rotor and 60% reduction in radial deflection. It is demonstrated that additive manufacturing shifts the focus from manufacturability constraints toward lower mass.
