“…The trend of the mean base bending moment coefficients are similar among the studies compared, and the C ¯ Mx and C ¯ My values, the latter from 0° to 90° and the former from 0° to 45°, obtained in this study are similar to those reported by Melbourne (1980). The higher magnitude of differences between the C ¯ My values are associated with wind directions greater than 45°, and the C ¯ My values obtained in this study are slightly higher than those reported by Melbourne (1980) and smaller than those reported by Sheng et al (2018). The scattering of results observed in Figure 10 could be caused using different criteria during the wind tunnel tests, primarily turbulence intensity ranges and the measurement of the wind speed reference, as described by Goliger and Milford (1988).…”

“…The maximum value of C ¯ Mx also occurs at 0° within the range of −0.55 to −0.62 for all models tested, while the maximum value of C ¯ My varies between 0.44 and 0.55, at wind directions from 60° to 75°. Figure 10 presents a comparison between the mean base bending moment coefficients for model M1 and those obtained by Melbourne (1980) and Sheng et al (2018). The model studied by Melbourne (1980) consisted of a rectangular cross section with a side ratio of 1.5 and an aspect ratio of 6, while the model studied by Sheng et al (2018) was square in plan with a side ratio of 1.0 and an aspect ratio of 5.…”

To investigate wind-induced torsional loads on rectangular tall buildings, five rigid scale models were tested in an atmospheric boundary layer wind tunnel. Each model was built with identical plan dimensions but different aspect ratios. Two terrain categories were experimentally simulated in the wind tunnel to evaluate each model under different wind directions. From synchronized wind pressure measurements, the values for the shear wind force, bending moment, and torsion moment at the base of each model were calculated. The results were normalized in terms of mean shear, bending, and torque coefficients. Variations of the coefficients obtained with respect to the aspect ratio of the models tested were analyzed. Based on the experimental results, a new parametric equation to estimate the torque coefficients at the base of rectangular tall buildings as a function of aspect ratio and wind direction was proposed. The base torque coefficients obtained with the proposed equation are in good agreement with the experimental results.

“…More than 70 % of the tests utilize this kind of multicomponent force and moment measure instrumentations to estimate aerodynamic loads [1]. With today's increasing requirements of aerodynamic experiments for aerospace vehicles, ground vehicles, modern and unique architectures, etc., customers are concerned much more about the performance of the wind tunnel force measurements [2]- [5]. Therefore, wind tunnel balance developing technology has been focused and promoted for more than 100 years to achieve higher accuracy of steady and fluctuating force measurements [6]- [9].…”

The traditional wind tunnel strain balance design cycle is a manual iterative process. With the experience and intuition of the designer, one solution that meets the design requirements can be selected among a small number of design solutions. This paper introduces a novel software integration-based automatic balance design optimization system (ABDOS) and its implementation by integrating professional design knowledge and experience, stepwise optimization strategy, CAD-CAE software, self-developed scripts and tools. The proposed two-step optimization strategy includes the analytical design process (ADP) and the finite element method design process (FEDP). The built-in optimization algorithm drives the design variables change and searches for the optimal structure combination meeting the design objectives. The client-server based network architecture enables local lightweight design input, task management, and result output. The highperformance server combines all design resources to perform all the solution calculations. The development of more than 10 balances that have been completed and a case study show that this method and platform significantly reduce the time for design evaluation and designanalysis-redesign cycles, assisting designers to comprehensively evaluate and improve the performance of the balance.

“…In fact, there is a good potential of harvesting energy from wind at high rise building areas (Glumac et al, 2018). In fact, build spacing and high rise buildings in the urban area cause to flow strong wind at base (pedestrian level at the ground) and also at the top of the buildings (Blocken and Stathopoulos, 2013;Blocken et al, 2016;Ricci et al, 2018;Sheng et al, 2018;Stathopoulos, 1985;Zheng et al, 2018).…”

An experimental setup is constructed to harvest energy from wind by means of oscillating of a body, structure or even trees. A vertical stem which can oscillate or bend is connected with a rack and pinion and finally pinion is connected with generator to harvest the electrical energy. Once the force is applied on the top of the stem, the connecting wire pulls the rack and pinion is in rotary motion and generates the power. The experiments are carried out for both applied static force and wind assist dynamic force. The experimental results show that the forces exerted on the stem are very much influenced by the stem height, the rack length for power generation. The results from wind assist experiments reveals that the sail size and the materials of both stem and sails play vital role on power generation. The constructed setup shows a good prospect on power generation from wind specially the places like highways, urban areas or any other places where the tree or any other object or structure oscillate.
