Tall buildings with irregular shapes and considerable heights are gaining popularity in creating the vertical cities around world. They also considered one of major energy consumers little regards to sustainability. building is wind-sensitive structure shape plays role determining wind loads, which usually govern design its lateral resisting system. Thus, evaluating loads properly designing an ...

In current work the Inerter-Connected Double Tuned Mass Damper (ICDTMD) is employed for structural control of a well-recognized benchmark 10-story linear shear building. The ICDTMD introduced to overcome practical limitations roof-top tuned mass damper inerter (TMDI), in which second terminal connected lower floors To this end, modification double (DTMD) with linking proposed not only exploit p...

This paper presents a new approach to the project of steel buildings, mainly focused on architectural, structural, and seismic design stairs. The objective is structural stair system capable controlling damage contributing bracing building. article begins with review standard (ATC, FEMA, EC8) which current criteria for buildings stairs are based. research based two spatial building models (A–B)...

In this paper, given a poset $(X,leq)$, we introduce some  drifts on a groupoid $(X,*)$ with respect to $(X,leq)$, and we obtain several properties of these drifts related to the notion of $Bin(X)$. We discuss some connections between fuzzy subalgebras and upward drifts.

Softening of beams near the moment connection can be regarded as one most convenient methods for retrofitting non-seismically designed buildings. This done by drilling beam web (aka RWS–Reduced Web Section) or cutting flanges RBS–Reduced Beam Section). Thus, becoming a cost-effective option and erection new buildings, while optimising use steel; making this high environmental impactful material...

In this paper a new distributed time synchronization algorithm is proposed for lossy wireless sensor networks with noisy local clock readings and inter-node communications. The algorithm is derived in the form of two asynchronous recursions of stochastic gradient type providing estimates of the parameters used to compensate drifts and offsets of the local clocks. A special modification of the a...

In this study, loading tests were conducted on RC structural frame with LGS partition wall and steel door as test specimens. the test, damage observation was to understand doors for each story drifts. Among observed ones thought be caused by residual deformation of seismic frame. It also found that when drift angle exceeds 1/200, required force more than 100N open it 1/100, could not opened.

Metal-containing mesoporous starches have been synthesized using a simple and efficient microwave-assisted methodology followed by metal impregnation in the porous gel network. Final materials exhibited surface areas >60 m² g-1, being essentially mesoporous with pore sizes in the 10-15 nm range with some developed inter-particular mesoporosity. These materials characterized by several technique...
