Introduction The introduction of Ultra-High-Performance Concrete (UHPC) has significantly advanced civil engineering, offering materials with high compressive and tensile strength and improved durability [1], [2].
NLFEA allows for the derivation of model uncertainty statistics tailored to specific failure modes, thereby refining safety factors to values typically accepted within the engineering community [25].

According to the regulations developed in US Army Corps of Engineers, Construction Engineering Laboratory, when the PCI is lower than 40%, overall renovation and primary maintenance are needed while regular repair needs to be enhanced when the PCI is between 40%-70%.

A Proof-of-Concept Study on Self-Centering Column Feet Equipped with Innovative Shape Memory Alloy Ring Springs Cheng Fang1,a*, Wei Wang1,b and Xiao Yang1,c 1Department of Structural Engineering, Tongji University, Shanghai 200092, China achengfang@tongji.edu.cn, bweiwang@tongji.edu.cn, c1432067@tongji.edu.cn Keywords: shape memory alloy (SMA); ring spring system; self-centering; column feet; cyclic performance.
The application of SMAs, especially superelastic (SE) NiTi SMAs, for civil engineering was first recognized in the 1990s.
SMA elements selected for civil engineering applications should preferably exhibit the following properties: 1) high material utilization efficiency, 2) low risk of damage, and 3) ease of installation.

So, it becomes one of the focuses of civil engineers on what the difference is between them.
A great deal of research about the floor acceleration response spectrum is done for nuclear reactor plant [1-4], and less study is done for ordinary civil building, especially there is few study done for super high rise building[5-7].

Such models often compromise between engineering judgment and the actual mechanics of the problem.
Furthermore, choice of the input variables is strongly affected by engineering judgement.
