“…Another article studying the seismic behavior of vertical shear links made of easy-going steel must be essentially mentioned (Daryan et al, 2008). Last but not least, the following paper is of extreme importance as it gives a comprehensive overview about the seismic design of masonry and reinforced concrete infilled frames (Moretti, 2015).…”

Cooperation between the architect and the civil engineer has nowadays become essential in any project for the client's requests' sake. This study was made to show this idea's importance and beneficial consequences. For this purpose, a 40-story dual-system high-rise building has been designed to resist moderate seismic and high wind loads. Three main models were formed: Starting with the net model, which is the regular model, followed by the mass irregularity models that were generated for the luxury floor desires (this irregularity was placed in two different locations, namely at the top and middle position), ending with the soft story irregularity models that were cited in the building's middle and bottom for the gym floor's need. The positions for each irregularity were tested and compared to those of the regular model under the effect of seismic load on one hand and under the influence of three different wind loads on the other. The required wind loads studied in this article were assigned from the wind speeds of 80, 100 and 120 mph. For these models' analysis, RSA using finite element method on ETABS was used.The results exhibited that the peak wind speed this building held was 110 mph for both irregularities. Furthermore, the seismically-designed high-rise buildings might not be safe enough to resist a wind load speed of 120 mph. In addition, the middle location is the most preferable locus for these irregularities to occur regarding wind and seismic loads because of its minor displacement, drift and base shear. Besides, it ensured the economic cost of the mass irregularity ($1,706,380), which is in turn less than that of the top position ($1,790,187). The same applies for the stiffness irregularity cost, requiring a budget of $1,632,310 in the middle position but an expense of $1,676,368 for the bottom locus. Although the irregularity's perfect location seemed unfamiliar, it pursues the sake of the client, the architect and the civil engineer alike.

“…Experimental studies have shown that behavior of an infilled frame is heavily influenced by interaction of the infill with its bounding frame (Al-Chaar et al, 2002;Dias, 2007;Kakaletsis and Karayannis, 2008;Shing, 1997, 2003;Shing et al, 1994). The Gap between infill and surrounding frame was found to be the most important parameter affecting the infill-frame behavior and unless this gap was not closed, the masonry infill contributed poorly to the lateral in-plane behavior of the frame (Moretti, 2015;Schmidt, 1989). Apart from the experimental investigations, a number of different analytical models (micro-and macro-models) have been developed to evaluate the infilled structures.…”

“…Macro-models, first proposed by Smith (1966), use the idea of equivalent strut at the compressed diagonal. There are many empirical approaches to determine the effective width of a single equivalent strut (Goutam and Sudhir, 2008;Kakaletsis and Karayannis, 2008;Raghavendra et al, 2014) or multi-struts (Asteris et al, 2011;Lavanya et al, 2015;Moretti, 2015;Zybaczynski, 2014). The second class of analytical models, generically named as micro-models, relies on complex analysis using the finite element method (FEM) investigated by several researchers starting with Mallick and Garg (1971), Liauw (1972), Page (1978), Lotfi (1992), Shing et al (1994), Riddington and Naom (1993), Shing (2008, 2012), Al-Chaar and Mehrabi (2008), Koutromanos et al (2011), Syed et al (2012), Kadid et al (2013), and Pavone (2014).…”

Considering the increased importance of robots nowadays, when no large factory or factory can work without robots, we want to present in the work the motion equations of the machine in an original form, both in terms of aspect and their deduction. The machine's motion equations can be used in dynamic calculations at any type of machine, whether it be a motor, a compressor, a lucrative machine, a robot, a system, a mechanism, a vehicle, a mechanical transmission, or any other type of car. The dynamics of systems is their real movement, the dynamic movement, in which the influences of three main factors interfere, which modify the kinematics of the mechanism when it moves really, dynamic. The first dynamic factor is the forces of inertia or the effect of inertial masses. The second important dynamic factor is that of the couplings, of the linkages within the respective machine mechanisms. The latter and the third dynamic factor represents the influence of system elasticity on its dynamic functioning. Only dynamic coefficient of inertia and the influence of kinematic couplings in the system were used in the analyzed sample. The dynamic coefficient due to elasticity and deformation in the system has not been taken into account since the overwhelming influence of the inertial forces is impacted by additional dynamic changes and also by the kinematic couplings in the system and the elastic deformations do not greatly influence the dynamics of the system in the case of the example remembered. If a robot was being discussed, things were similar, as in the case of various vehicles and various mechanisms and machines. However, for rigid memory transmissions, elastic deformations are important, which is why they should be considered in such systems.
