Summary
Social and organizational factors significantly impact construction safety performance by shaping the safety climate. This study developed a structural model to understand these influences for better safety interventions.
Area of Science:
- Construction Management
- Occupational Safety and Health
- Structural Equation Modeling
Background:
- The construction industry is a high-risk sector globally.
- Ensuring construction safety is a critical concern for professionals and researchers.
- Economic development and industrialization exacerbate construction hazards.
Purpose of the Study:
- To develop a structural model of factors influencing construction safety performance.
- To identify key components affecting safety outcomes in construction projects.
- To enhance understanding of safety performance indicators.
Main Methods:
- A two-stage Structural Equation Model (SEM) was employed.
- Data collected via questionnaire study (n=230).
- LISREL 8.8 software used for structural model analysis.
Main Results:
- A well-fitting structural model was achieved (GFI=0.92, RMSEA=0.04, CFI=0.98).
- Social and organizational constructs were found to influence safety performance.
- The safety climate acts as a mediating component in this influence.
Conclusions:
- The validated structural model offers insights into safety performance drivers.
- It aids in understanding the relationship between safety indicators and contributing factors.
- Provides a basis for stronger recommendations for construction safety interventions.

01:22Design Consideration
642
Designing a structure involves a series of considerations, primarily the material's ultimate strength, calculated through tests that measure changes under increased force until the material reaches its breaking point or limit. The ultimate load, where the material breaks, is divided by its original cross-sectional area, resulting in the ultimate normal stress or strength. The ultimate shearing stress is another significant factor taken into account.

Surveying near highways, rough terrain, or power lines involves significant risks. Working along highways is particularly dangerous and requires the use of warning signs and flagmen. It is safest to avoid working directly on roads and use offsets whenever possible. When highway work is unavoidable, it must follow all safety guidelines. Surveyors should wear bright clothing, such as orange reflective vests, to ensure visibility to motorists, coworkers, and hunters. In construction zones, wearing...

01:23Design of Prismatic Beams for Bending
680
The design of prismatic beams, structural elements with a uniform cross-section, focuses on ensuring safety and structural integrity under load. The design process begins by determining the allowable stress, either from material properties tables, or by dividing the material's ultimate strength by a safety factor. This safety factor is essential for accommodating uncertainties, and varies depending on the material—timber, steel, or concrete—with each having unique strength and...

01:28Internal Loadings in Structural Members: Problem Solving
1.8K
When designing or analyzing a structural member, it is important to consider the internal loadings developed within the member. These internal loadings include normal force, shear force, and bending moment. Engineers can ensure that the structural member can support the applied external forces by calculating these internal loadings.
To illustrate this, let's consider a beam OC of 5 kN, inclined at an angle of 53.13° with the horizontal and supported at both ends. Determine the internal...

1.5K
Indeterminate structures refer to structures where internal forces and reactions cannot be determined using only the equations of static equilibrium. Indeterminate structures have more unknown forces and reaction forces than equations of static equilibrium that can be used to determine them. Indeterminate structures are often used in engineering to create complex, efficient, and aesthetically pleasing structures. There are various types of indeterminate structures used in engineering and...

01:20Method of Superposition
2.2K
The method of superposition is a crucial technique in structural engineering, used to analyze the effect of multiple loads on beams. This approach involves calculating the deflection and slope for each load on a beam separately, and then summing these effects to determine the overall impact. It is applicable only when the beam material remains within its elastic limit, ensuring that deformations are linearly elastic.
