SECOND-ORDER ANALYSIS FOR LONG SPAN STEEL STRUCTURE PROTECTING A HERITAGE BUILDING
INTRODUCTION Second-order analysis has been widely referred in codes and claimed by structural analysis software. There are actually many types of second-order analysis with the simplest one that considers only the P-△ effect and other more advanced ones that include the P -△ - δ effect with careful consideration of initial imperfections as well as plastic hinges. In Hong Kong, which has one of the most highest worlds density in high-rise steel composite buildings with height greater than 150 m, this method of design is widely used and the success is partly due to the use of one-element-per-member model which saves time and efforts in design and improves safety as well. This paper is concerned with the protection of a heritage building.
