“…Mirrors play a significant part in the field of optics and have a wide usage in developing renewable energy technology such as use of concave, and convex mirrors in solar panels (Siahaan and Hartono, 2019). Along with lenses and mirrors the theorems have significant use cases in Arch Bridges (Gönen and Serdar, 2021;Lan et al, 2020;Sun et al, 2023) when one is trying to construct a bridge as shown in Figure 5 with the help of a simulated miniature model of that bridge as a reference.…”

“…This theorem has significant usage in construction and cost-estimation of jewelleries, buildings, and infrastructures like-solar panels with concave/convex mirrors (Siahaan and Hartono, 2019), doors, windows, and bridges (Gönen and Serdar, 2021;Lan et al, 2020;Sun et al, 2023) as shown in Figure 5. To apply paint, polish, coating or even cleaning such structures the estimation of area enclosed by arc and chord (chord is created by joining the endpoints of the arc) is required.…”

Arcs are one of the fundamental concepts of circles and are also used in real-life objects such as bridges, jewelleries, buildings, tools etc. In this paper we have proposed theorems for arcs of different circles having the same arc-angles. The proposed theorems have applications in concave/convex surfaces such as lenses and mirrors, buildings, infrastructures, bridges, jewelleries, and mechanical tools such as a sickle.

The Changjinghuang Railway Xinjiang Xizhi Bridge is a (90 + 180 + 90) m continuous beam arch bridge, and the arch rib steel pipe installation adopts “short bracket assembly and overall lifting method”. In order to ensure the accuracy of closure, the stress and deformation of the arch rib and bracket must be strictly controlled. Midas Civil is used to establish the finite element model to simulate the overall lifting construction process of the arch rib. Based on the model, the stress and deformation of the arch rib and the supports are analyzed, and the determination method of the horizontal cable force under temperature variations is proposed. The results show that the stress and deformation of the arch rib and bracket meet the requirements. Considering the variation of temperature, the tension force of the horizontal cables is taken as 200 t. The construction plan proposed under the guidance of numerical calculation results has been proven by practical engineering to meet the requirement of closure accuracy, which can be used as a reference for similar projects.

The steel box arch bridge in this study will be subjected to various temperature effects from the construction to the operation stage, including the cement hydration heat effect and the sunshine temperature effect caused by an ambient temperature change. Therefore, it is very important to control the temperature effect of steel box arch bridges. In this study, the newly built Dafeng River Bridge is selected as the steel box arch bridge. This study aims to investigate the temperature effect including hydration heat and the sunshine temperature effect of the construction process of a rigid frame-tied steel box arch bridge. The manuscript presents that the heat dissipation performance of concrete decreases with the increase in the thickness of a mass concrete structure. The average maximum temperature values of layer No. 3 are about 1.3, 1.2, and 1.1 times the average maximum temperature value of layer No. 1 for the mass concrete of the cushion cap, main pier and arch abutment, respectively. The higher the molding temperature is, the higher the maximum temperature by the hydration heat effect is. With each 5 °C increase in the molding temperature, the maximum temperature at the core area increases by about 4~5 °C for the mass concrete. The pipe cooling method is conducive to the hydration heat control effect of mass concrete. Based on the monitored temperature change and displacement change, the influences of daily temperature change on the steel lattice beam and arch rib are analyzed. A temperature rise will cause the structure to have a certain camber in the longitudinal direction, and the longitudinal or transverse displacement caused by the sunshine temperature change is no less than the vertical displacement. Due to the symmetrical construction on both sides of the river, the arch rib deformation on both sides presents symmetrical synchronous changes. Based on 84 h of continuous temperature monitoring on-site, the changing trends of the arch back temperature and ambient temperature are consistent and their difference is small during 1:00~4:00 in the morning, which is determined as the appropriate closure time for the newly built Dafeng River Bridge.
