Job Hazard and Safety Analyisis, JHA and JSA - SafetyInfo

A job hazard analysis is a technique that focuses on job tasks as a way to identify hazards before they occur. It focuses on the relationship between the worker, the task, the tools, and the work environment. Ideally, after you identify uncontrolled hazards, you will take steps to eliminate or reduce them to an acceptable risk level.

Beam Stress & Deflection | MechaniCalc

Many structures can be approximated as a straight beam or as a collection of straight beams. For this reason, the analysis of stresses and deflections in a beam is an important and useful topic. This section covers shear force and bending moment in beams, shear and moment diagrams, stresses in beams, and a table of common beam deflection formulas.

How to Use Steel Fibers in Concrete| Concrete …

30/3/2012 · How much steel fiber is added to a concrete mix depends on the objectives: cost savings, increased joint spacing, or structural improvement. Steel fiber dosages can be as light as 8 pounds to as much as 200 pounds per cubic yard. Increasing the percentage of fibers in a mix allows specifiers to increase the distance between joints.

Numerical and Experimental Analysis of the Shear …

Abstract. Shear performance of plain UHPC (ultrahigh-performance concrete) construction joints is studied in both experimental and analytical ways. In push-off tests, three different contact surfaces of the construction joint were considered, while the case without any joint was provided for the reference.

Reinforced Concrete Water Tank Design Requirements

The design of reinforced concrete water tank is based on IS 3370: 2009 (Parts I – IV). The design depends on the location of tanks, i.e. overhead, on ground or underground water tanks. The tanks can be made in different shapes usually circular and rectangular shapes are mostly used. The tanks can be made of reinforced concrete or even of steel.

6 Types of Concrete Cracks and What They Mean | …

When you hear a concrete mix has a strength of 2000, 3000, 4000, or 5000+ PSI, it is referring to the pounds per square inch it would take to crush that concrete slab. When it comes to residential concrete slabs, overload of the actual slab isn't all that common.
