Based on the summary of existing pounding force analytical models, an updated pounding force analysis method is proposed by introducing viscoelastic constitutive model and contact mechanics method. Traditional Kelvin viscoelastic pounding force model can be expanded to 3-parameter linear viscoelastic model by separating classic pounding model parameters into geometry parameters and viscoelastic material parameters. Two existing pounding examples, the poundings of steel-to-steel and concrete-toconcrete, are recalculated by utilizing the proposed method. Afterwards, the calculation results are compared with other pounding force models. The results show certain accuracy in proposed model. The relative normalized errors of steel-to-steel and concreteto-concrete experiments are 19.8% and 12.5%, respectively. Furthermore, a steel-to-polymer pounding example is calculated, and the application of the proposed method in vibration control analysis for pounding tuned mass damper (TMD) is simulated consequently. However, due to insufficient experiment details, the proposed model can only give a rough trend for both single pounding process and vibration control process. Regardless of the cheerful prospect, the study in this paper is only the first step of pounding force calculation. It still needs a more careful assessment of the model performance, especially in the presence of inelastic response.

“…In many cases, these earthquakeinduced poundings may cause functionality to be disabled or even more serious results, such as large plastic deformations and splintering and collapse of main structural components of buildings. For bridges girder, dislocations or fallings may occur due to vertical or horizontal poundings [6].…”

“…The damage of structures in strong earthquakes causes economic loss, casualties and downtime. Pounding between adjacent structures is the one of the reasons that causes such damage and is commonly observed after strong earthquakes, e.g., 1971 San Fernando earthquake [1], 1985 Mexico earthquake [2], 1989 Loma Prieta earthquake [3], 1999 Taiwan Chi-Chi earthquake [4], 2008 Wenchuan earthquake [5], 2011 Christchurch earthquake [6,7], and 2015 Gorkha Earthquake [8]. Usually, the pounding becomes the source of local damages and in some cases it may even lead to collapse of the structures.…”

Pounding of two adjacent structures is one of the factors that cause damage and hinder sustainable use of reinforced concrete (RC) frame structures under strong ground motion excitations. This study developed a pounding analysis method with a refined beam-column element in order to solve the pounding problem between two RC frame structures. The analysis method combines the fiber beam-column element model with the element sections discretized into concrete and longitudinal rebar fibers, the Hertz-damp contact element model to describe the pounding between beam-column elements, and the method to integrate the pounding force into the system dynamic equilibrium equation. The pounding can be considered either at the level between the story slab to slab or at the level between story slab to mid-column. The application of the proposed method in pounding analyses to provide a rational seismic separation gap between two adjacent RC frame structures is finally conducted to increase their safety and sustainability under strong earthquakes.

“…Li et al evaluated influences of abutment excitations on the pounding behavior of a system consisting of a single bridge span with various fundamental frequencies and its abutments experimentally [16]. Wang and Shih presented a case study on the sliding of bridge decks of a multispan concrete bridge and pounding at abutment-backfill under the 1999 Chi-Chi earthquake [17]. Huo and Zhang studied effects of pounding and skewness on the seismic behaviors of typical three-span bridges in California [18].…”

The pounding issue between decks in the earthquake has been a great concern of many researchers, but the research on the deck-pier pounding issue was inadequate. In this paper, a simplified SDOF method was proposed to study the issue for simply supported girder bridges. Theoretical analysis, shaking table test, and finite element analysis were conducted to study the applicability of the simplified SDOF method in longitudinal deck-pier poundings. A whole structural model and a SDOF model for the longitudinal pounding issue were also established to study influences of the pier stiffness and the pier mass on longitudinal pounding responses. It is shown that the simplified SDOF method can estimate the pounding force and deck displacement fairly accurately for almost all cases. The pier mass has little effect on pounding responses except for bridges with very rigid piers, but the pier stiffness has a great influence. The larger the pier stiffness is, the higher the peak pounding force is.
