Special Issue Information

Dear Colleagues,

In civil engineering, some structures and construction possess some kind of symmetries and asymmetries, such as buildings, bridges, etc. The advantages of the symmetry and asymmetry of a structural system in simplifying the mathematical model to solve both the statics and dynamics problems are quite obvious. Additionally, the application of symmetry and asymmetry in the design and construction of civil structures can effectively lead to attractive architectural appearance and reduce the time cost. In the field of structural health monitoring (SHM), the complicated monitoring point arrangement can be simplified by making full use of the principles of symmetry and asymmetry. This Special Issue invites original technical papers that focus on the use of symmetry and asymmetry in structural engineering and structural mechanics.

To facilitate the first application of the novel concrete-filled built-up K-joints with different brace sections in truss bridges, the present paper aims to determine their practicability through a comparison with integral joints. First, a structural analysis was carried out using the MIDAS CIVIL software to evaluate the loading applied to the structure. Additionally, boundary condition analysis was carried out. After that, the symmetric multi-planar joints were developed, using Abaqus 6.14 for the strength verification and the failure mode identification. These were followed by the multi-planar joints estimate cost. The results indicated that for positive bending, the novel joint deformed by 2.01 mm, compared to 4.83 mm for the integral joint in the serviceability limit state. These deformations were equal to 5.58 mm and 7.68 mm, respectively, in the negative bending. Verification under the ultimate limit state indicated a deformation of 10.43 mm for the novel joint type and 16.59 mm for the integral joint in the positive bending, whereas deformations of 15.89 mm and 16.82 mm were indicated in the negative bending. Moreover, a failure mode analysis showed a buckling of the arc yielding for the novel joint type and a buckling of the gusset plate for the integral joint. Finally, the results showed that the novel type of joint was more expensive by about CNY 111,286.06. Full article
