“…Abey et al discuss a method for improving the bridge seismic properties by using the "parameter-based impact factor" that was developed by factor theory. The factors considered in the factor analysis are longitudinal reinforcement percentage, concrete compressive strength, reinforcement yield strength, transverse tie spacing, and column height [4]. Yu et al aim to study the seismic performance of RC short and long columns with welded stirrups.…”

Reinforced concrete antiseismic wall structure has great load-bearing capacity and resistance to lateral displacement and is widely used as high-rise and super high-rise buildings. At present, in the seismic testing of buildings, the vibration signals that simulate earthquakes are transmitted through a wired transmission system for analysis after a certain amount of processing, and the seismic performance of the building is tested. The purpose of this paper is to analyze and study the seismic resistance of a newly fabricated lightweight herringbone braced seismic wall based on ZigBee sensor technology. In this paper, firstly, the research and exploration of the building seismic capability detection system using ZigBee technology wireless sensor are carried out, and the building seismic capability detection system is a wireless sensor network using ZigBee technology; it measures the seismic performance of the building by detecting the acceleration values of key parts in the building model. Then, the seismic design response spectrum is proposed, and the modal analysis is carried out at the same time, and the mode decomposition response spectrum method is given. Then, the seismic performance of the reasonable RC support lightweight herringbone support seismic wall was analyzed, and the seismic performance of the lightweight herringbone support structure was studied at the same time. The experimental results show that with the increase in the size of the RC support section, the bearing capacity and seismic performance of the lightweight herringbone support seismic wall are improved. The displacement ductility coefficient obtained is greater than 4, and the energy dissipation coefficient is 1.56, which meets the seismic requirements of the structure.

“…Interest in the Global Positioning System (GPS) has increased in recent years, particularly in regard to the precise point positioning (PPP) technique due to its ability to generate accurate instantaneous positioning (Yigit and Gurlek, 2017;Yigit, 2016;Bhagat and Wijeyewickrema, 2017) to detect the dynamic characteristics of structures (Breuer et al, 2015;Ting et al, 2013a;Moschas and Stiros, 2013), especially suspension bridges (Moschas and Stiros, 2011;Ting et al, 2010aTing et al, , 2010bTing et al, and 2009Schaal and Larocca, 2009;Abey et al, 2017;Bayat et al, 2017;). Nonetheless, there have been few applications in the monitoring of buildings.…”

During the earthquake in Emilia (Italy) of 2012, ca. 30 permanent GPS stations were in operation within a radius of about 100 km from the epicenter, each equipped with an antenna rigidly fixed to the host building and sampling the GPS signal at a high rate (> 1 Hz). From the recording of the GPS measurements, the instantaneous displacements s(t) in the North-South and East-West directions of the phase centers of the single GPS antennas at each permanent station during the most important seismic sequences were calculated in kinematic mode. Subsequently, for each of the two displacements considered as two distinct external forces, the elastic response spectra of the building were determined and from them the two periods of vibration T along two orthogonal directions coinciding with the walls of the building were extracted. The experimentally obtained periods of vibration were compared with those inferable from the technical literature. In this way, a sufficiently large sample was obtained per building type, geometry (square, rectangular, regular or irregular planimetry), height (from a minimum of 4 to a maximum of 20 m) and materials (masonry, reinforced concrete, etc.). From the computational point of view, the study confirmed that GPS is an emerging tool for monitoring dynamic displacements and the experimentally estimated value of T is always lower than the one estimated with the formulae reported in the literature. The limitations of the study lie in the impossibility to choose a priori the geometry and/or structural type of the building hosting the GPS station.
