Strength of Damaged Steel Sections
Even though the damaged structure may appear to be intact, the ability to resist earthquake loads, wind loads and other abnormal loads is severely reduced and catastrophic failure may result without warning.

Changes in AS4324.1-2017 – What Does This Mean for Existing Machines?
In contrast to previous revisions, AS4324.1-2017 states that the standard should be used to risk assess existing machines for continued use, upgrades or modification. This clarifies the importance of AS4324.1 compliance for existing machines and may impact current risk management strategies, systems and procedures for these machines.
P-F Curves and Asset Management
The P-F curve is a common representation of an assets life cycle based on the concept of the relationship between “Potential Failure” (P) and “Functional Failure” (F). Typically, P-F curves have been used to assist reliability analysis of mechanical equipment such as pumps, drives, bearings etc. However, the concept of the P-F curve can be applied to any asset. ASPEC frequently utilise P-F curves as a useful tool to communicate information regarding asset condition and status within the asset lifecycle.
Summary of Changes in New Revision of AS4324.1-2017
This article provides a high level summary table of changes in the AS4324.1-2017 standard and likely implications for new and existing machines.
Changes in AS4324.1-2017 – Use of Partial Load Factors
AS 4324.1-2017 has been recently published. One of the changes in the standard is the use of partial load factors that are consistent with the Limit States Design method used in structural design.
Australian Standard AS4324.1-2017 Now Published
Standards Australia recently published the latest edition of AS4324.1 Mobile equipment for continuous handling of bulk materials – General requirements for the design of steel structures in December 2017. The standard was first published in 1995 and the revision has been prepared by the Standards Australia ME43 committee to update it and clarify some areas which have caused ambiguity over the last 20 years of use.
