Connection fixity considerations for steel frame modelling
This report concerns the modelling of joints when using computer programs. In some cases, engineers are applying rotational releases to joints in models but subsequently designing the connections as rigid. This leaves a fundamental mismatch between analysis and design which may lead to unsafe structural connections argues a reporter.

Incompetent design of simple steel beams
This report concerns designs for simple steel beams submitted to building control bodies under Part A of the Building Regulations. The reporter, a checking engineer for a building control body, was not able to accept the effective length and restraints assumed in a number of submitted designs. Most originated from individuals who used proprietary structural design computer packages without, i...

Building regulations checking
A reporter’s firm has been carrying out building regulations checks for 25 years, but it is only in the last six or seven years (say 2000-2006) that concerns have arisen, some of which are described below.

Concrete grade confusion in software
A reporter noticed that the design calculation report generated by a proprietary software package called for ‘concrete characteristic strength = 45N/mm2’, but did not confirm whether this refers to the cylinder or cube strength.
