Masonry infill walls are critical components of reinforced concrete (RC) frames, which may be damaged even under earthquake events moderate intensity, thus resulting in significant losses. Recent experimental and numerical studies have investigated innovative solutions for protecting these by reducing their interaction with the RC frame. Among these, specially shaped rubber joints were develope...

This study investigates the performance of novel metamaterial-based barriers and foundation on mitigating waves transmitting from a vibrational source to surrounding soil. An active isolation system is wave barrier built close vibration reduce radiating structure research reports efficacy proposed using an excitation field test, thereby expanding applicability such beyond passive isolation. The...

in this paper we get some results and applications for duals and approximate duals of g-frames in hilbert spaces. in particular, we consider the stability of duals and approximate duals under bounded operators and we study duals and approximate duals of g-frames in the direct sum of hilbert spaces. we also obtain some results for perturbations of approximate duals.

in this paper, g-dual function-valued frames in l2(0;1) are in-troduced. we can achieve more reconstruction formulas to ob-tain signals in l2(0;1) by applying g-dual function-valued framesin l2(0;1).

Hilbert frames theory have been extended to frames in Hilbert $C^*$-modules. The paper introduces equivalent $*$-frames and presents ordinary duals of a constructed $*$-frame by an adjointable and invertible operator. Also, some necessary and sufficient conditions are studied such that $*$-frames and ordinary duals or operator duals of another $*$-frames are equivalent under these conditions. W...

in this paper we proved that every g-riesz basis for hilbert space $h$ with respect to $k$ by adding a condition is a riesz basis for hilbert $b(k)$-module $b(h,k)$. this is an extension of [a. askarizadeh,m. a. dehghan, {em g-frames as special frames}, turk. j. math., 35, (2011) 1-11]. also, we derived similar results for g-orthonormal and orthogonal bases. some relationships between dual fram...

Despite achieving consensus and having current knowledge on the behaviour contribution of masonry infill walls, there remain unresolved issues regarding their nonlinear as a method for strengthening existing reinforced concrete (RC) frames with effective modifications, primarily infills interconnection frames. The challenge safely economically designing competent walls is to utilise stiffening ...
