“…It can be seen from Figure 9 that the diference between the experimental cracking load and the cracking load calculated in this paper is very small. In references [13,20,21], the maximum COV of the cracking load is 11.49. So the calculation of cracking load in this paper is accurate.…”

“…Tree reinforcement forms have been completed by Wei Fan et.al, strengthened columns with two-end UHPC jackets are the better strengthening method [9]. Te reinforcement method is used to improve the crashworthiness of bridge piers, and the impact of various parameters on the crashworthiness of bridge piers is analyzed by the response surface model [12,13]. Te combination of UHPC and steel structure has also been proven to have good impact resistance.…”

“…By adding the UHPC layer on the tensile side, the stifness can be greatly improved, the formation of cracks was delayed, and the peak load was slightly increased [22]. Te experimental results of reference [13] show that the fexural resistance of UHPC-NC can be greatly improved by installing proper longitudinal reinforcement in the UHPC layer [19].…”

In this study, models for calculating the cracking load and a peak load of the UHPC-NC structures are established. The effects of UHPC's high tensile strength, reinforced steel bars in NC, reinforce steel bars in UHPC, and prestress tendons in UHPC on cracking load and peak load are considered. In the cracking load model, UHPC is considered to be elastic and the stress distribution is triangular, the stress of steel bars and prestressing tendons is also calculated according to the plane section assumption and elastic theory. In the peak load module, UHPC is assumed to be partially elastic and partially plastic. The plastic part is represented by a rectangular stress block diagram, and the stress value reduction factor and rectangular stress frame height reduction factor are obtained by trial calculation. Compared with the experimental data of UHPC-NC beams with different types of combinations collected from references, the calculated results have a high matching degree, which is suitable for various types of UHPC-NC, both cracking loads and peak loads.

To ensure the safety of ships and bridges at the same time during collisions, a new type of bridge pier protection system is proposed, in which one is composed of corrugated steel plates, bolts, and corrugated steel pipes (CSP), and the other is composed of ordinary steel plates, bolts, and corrugated steel pipes (OSP). To study their anticollision performance, a pendulum impact test and numerical simulation were carried out. Comparing the test results with the simulation results, it was shown that the simulation results are basically consistent with the test results. Then, the influence curves of the impact velocity, specimen thickness, weight, and frequency are analysed to evaluate the anticollision performance of CSP/OSP and optimize their structure. When the impact energy is low, the peak values of the lateral impact force and lateral displacement of the column equipped with OSP are all smaller than those of the column equipped with CSP. When the impact energy is high, the peak values of the lateral impact force and lateral displacement of the column equipped with OSP are larger than those of the column equipped with CSP. However, under the same impact energy, the total energy peak value of the CSP specimen is larger than that of the OSP specimen. Results can provide a certain numerical analysis basis for the structural design and research of new types of corrugated steel protection system for bridge pier.
