So, it is unreasonably to attribute engineering accidents to the professional ethics of engineers unilateral and isolated.
Why do the engineers not play a role in it?
These managers often ignore the engineers make engineering decisions based on the engineering and technical knowledge.
The engineering community includes engineers, workers, investors, managers and other stakeholders.

Abstract: Steel bar defect detection in concrete is an important content of civil engineering structure detection.
Background In the construction of civil engineering, there are always quality problems of steel bar.For example, steel bar fracture and dislocation.
The purpose of this study is to find out the nondestructive testing method of steel defects in concrete,and to solve practical engineering testing requirements. 2.Equipment and working principle The equipment we used is magnetic scanner.
The technology provide accurate information , significantly reduce the testing time and improve the efficiency of detection greatly.So the non-destructive technology for defects of steel bar can be applied to general engineering applications.

Moreover, aggregates availability deriving from river reduces over time, almost 60% of civil engineering infrastructures in world are made with concrete.
Aggregates availability originating from river and also natural rock reduces over time, because almost 60% of civil engineering infrastructures in the world made with concretes [5, 6, 7].
With these results it is potential to use these hybrid high-strength concretes as structural elements at civil engineering infrastructures especially at earthquake-prone areas such as Indonesia.

Calculating Dynamic Strengths of Concrete Subjected to Impact Load Zainab Hasan Abdulabbas1,a*, Layth Abdul Rasool Alasadi2,b 1Department of Civil Engineering, University of Kufa, Najaf, Iraq 2Department of Civil Engineering, University of Kufa, Najaf, Iraq azainab.alhasnawi@uokufa.edu.iq, blaitha.alasadi@uokufa.edu.iq Keywords: dynamic properties, impact load, sustainable concrete, CEB-FIP models code, metal waste.
As known, the dynamic properties are so helpful in the strategy that deal with civil constructions put in danger of impact loads like runways, gas explosions, etc.
In this range, dynamic loads in the civil constructions at level of quasi-static strain were predicted.

Methods of assessing progressive collapse-resisting capacity Zhang Haohao1,a, Shu Ganping1,b, Zhu Zheda1,c College of Civil Engineering, Southeast University, Nanjing, 210096, China azhhao_2006@163.com, bsgp0818@vip.sina.com, cmegatronzzd@gmail.com Keywords: progressive collapse, alternate path, tie forces Abstract.
It has been one of the hotspots of the civil engineering study.
The similar risk assessment is used widely in earthquake engineering.
Recently, there are a few progressive collapse-resisting articles in many developed country’s design code, but these articles are not specific, for example, no detailed standard parameter, so that the engineer can’t use these articles well.
