“…Liu et. al [15] studied the responses of tall flexible structures such as TV towers when the vertical eccentricities between the discrete nodes and the corresponding centroids of investigated lumps are considered. Çakır [16] simulated a 3-D backfill-structure-soil/foundation interaction phenomenon using the finite element method in order to analyze the dynamic behavior of cantilever retaining wall subjected to different ground motions.…”

RC chimneys are occupying the most important part of industrial factories that they are utilized for removing the waste and hot gases to the atmosphere. Nowadays, in order to meet the requirements of the codes related with the environment needs, the height of these slender structures increase that makes them more vulnerable to seismic loads. Therefore, the overall dynamic behavior of these tall and slender structures should be understood by also considering the effect of underlying soil. In this study, the dynamic seismic response of a model chimney was determined by considering openings, foundation and underlying soil separately. Findings of this study revealed that soil-structure interaction (SSI) is an important phenomenon that effects the dynamic response of reinforced concrete (RC) chimneys.

Summary The time delay effect is prominent for the slender structures under the action of near‐fault pulse‐like earthquake excitation. It takes time for the earthquake motion to transfer from the base to other portions of the structure. This paper proposes an explicit‐based fiber line element with its analytical framework to capture the time delay effect when excitated by earthquake motion. The object‐oriented technique (C++) is used to code the integrated analysis framework. Newly designed classes are integrated to perform the explicit analysis parallelly. The nonlinear material model is also incorporated into the proposed element. The verification of the proposed element shows the time delay effect can be spotted inside the structure. The proposed element can provide a reasonable transient dynamic response under both static and dynamic loadings. The basic and higher vibration model can be aroused if the proper frequency is inputted. A slender reinforced concrete bridge pier is numerically modeled by the proposed element, and its seismic response characteristic under the action of the qualified multipulse near‐fault earthquake motion is analyzed. The results show the seismic response within the pier is transferred from bottom to top in a distinct time delay. In a statistical sense, the typical increasing ratio of relative displacement for S/R and P/S is 4.9% and 8.1%, respectively. Directly using the earthquake motion recorded at the seismic station may underestimate the seismic demand.
