Abstract TADAS dampers are a type of passive structural control system used in the seismic design or retrofitting of structures. These types of dampers are designed so that they would yield before the main components of the structure during earthquake. This dissipates a large portion of the earthquake’s energy and reduces the energy dissipation demand in the main components of the structure. Considering its suitable performance, this damper has been the subject of numerous studies. However, there are still ambiguities regarding the effect of the number of these dampers on the retrofitting of reinforced concrete (RC)… More >

Abstract This study focuses on advanced finite element (FE) analyses on The Church of Nativity located in Bethlehem (Palestine), one of the most historic structures in the world. To ensure the model quality, a 3D FE model was created using two types of typical commercial software, DIANA FEA and SAP2000. From analyses, one of the expected behaviors for this kind of masonry structure “low modal period” was found. The seismic behavior of the church was studied using pushover analyses, which were conducted using DIANA FEA. The first unidirectional mass proportional load pattern was created in both… More >

Abstract The equivalent diagonal strut models of infill wall mainly include the single strut model and multi-strut model. Firstly, several equivalent strut models and their characteristics are introduced in this paper. Then, model analysis and pushover analysis are carried out on infilled frame models with the aid of the software SAP2000. Two typical single strut models and a typical three-strut model are used to simulate the panel of the frames respectively. It is indicated that the period reduction factor of the frame with a three-strut model is close to the value recommended by the current code. More >
