In this paper, a control strategy to reduce the vibrational response of adjacent buildings under seismic excitation is presented. The proposed strategy combines passive linking elements with an active decentralized H∞ control system. The overall active-passive control system admits decentralized design and operation, and achieves an excellent vibrational reduction when the active control system...

Periodic sampling of 30 independent monitors, initially active with the Formosan subterranean termite, Coptotermes formosanus Shiraki, was conducted to evaluate the effects of soil treated with imidacloprid on nearby termite activity. Monitors were located adjacent (1-3 m) to the buildings. Soil around and under the buildings was treated with 0.05% imidacloprid. None of the termites collected s...

A numerical approach is presented for an inequality problem arising in the earthquake analysis of adjacent buildings. This problem concerns the unilateral contact-impact between neighboring buildings, when friction and P-delta effects are taken into account. The proposed numerical approach is based on a double discretization, in space and time, and on optimization methods. First, the Finite Ele...

The creation of 3D models of ancient sites has often been focused on their major monuments only. This is logical, given the high costs of traditional 3D modeling. Thus, to efficiently reconstruct entire sites like cities, a large number of domestic buildings and workshops need to be generated automatically. Their appearance should follow the aesthetic and statutory architectural rules of the co...

This paper presents a novel model to assess the risk of adjacent buildings in tunnelling environments based on Extended Cloud Model (ECM). ECM is an organic integration of Extension Theory (ET) and Cloud Model (CM), where ET is appropriately employed to flexibly expand the variable range from [0, 1] to (-∞, +∞), and CM is used to overcome the randomness and fuzziness during the gradation of eva...

Abstract Since the safety and stability of original tunnel structure are easily affected by adjacent foundation pit excavation, it is strongly necessary to study deformation evolution tunnels during excavation. With regard two cases that adjacently located at right bottom pit, influence different supporting methods, including pile support, bolt pile-bolt shotcrete-bolt on was investigated basis...
