“…The results show that concrete shrinkage and creep have no effect on the axial force of the whole section of the structure system, but it has great influence on the bending moment of the whole section of the structure. Liu et al [8] establishes a plane finite element model to analyze the stress of concrete-filled steel frame tied arch bridge under the action of temperature load and dead load. The results show that changing the rise-span ratio has a great influence on the axial force of the structure under dead load and the internal force caused by the whole temperature change.…”

In order to further improve the crack resistance of concrete engineering, a numerical simulation method is constructed to study the effect of temperature on the fission of concrete. Based on the finite element method, the mathematical model is constructed, and the numerical calculation and image display are used to simulate and analyze the engineering problems. The temperature sensor is used to observe the whole variation law of typical temperature field, and the temperature of concrete entering and pouring is obtained. Thus, the temperature control real-time automatic acquisition system is set up. According to the temperature field and temperature stress distribution rules, the ideal temperature control curve model of concrete is proposed. Finally, the numerical calculation and experiment of the model are carried out. The results show that the maximum surface stress level decreases in varying degrees after different surface insulation measures are taken, and if the thermal insulation material's β ≤ 10 kJ/m 2 h℃, the maximum surface stress of concrete can be reduced to 0.06~0.14 MPa. In this paper, it is shown that the negative effect of the large diurnal temperature difference on concrete surface insulation can be controlled.

“…It is well known that Fig. 12 TSIF for the surface crack of depth d/l = 1 [187] the presence of crack reduces the dynamics response of structure. The existing studies are yet to input sufficient explanations about the dynamic behaviour of structure under distributed temperature across the structure.…”

Fatigue damage is a concern in the engineering applications particularly for metal structures. The design phase of a structure considers factors that can prevent or delay the fatigue and fracture failures and increase its working life. This paper compiled some of the past efforts to share the modelling challenges. It provides an overview on the existing research complexities in the area of fatigue and fracture modelling. This paper reviews the previous research work under five prominent challenges: assessing fatigue damage accurately under the vibration-based loads, complications in fatigue and fracture life estimation, intricacy in fatigue crack propagation, quantification of cracks and stochastic response of structure under thermal environment. In the conclusion, the authors have suggested new directions of work that still require comprehensive research efforts to bridge the existing gap in the current academic domain due to the highlighted challenges.
