FIRE RESISTANCE OF ENERGY EFFICIENT FLOOR STRUCTURES

Parameters affect the fire resistance performance of floor systems

Stainless steel structures in fire

The initial material cost of structural stainless steel is about four times that of structural carbon steel, due largely to the expense of the alloying elements and the relatively low volume of production. Given broadly similar structural performance, additional areas of benefit need to be identified and exploited in order to establish stainless steel as a viable alternative material for constr...

The Current Situation and Development of Fire Resistance Design for Steel Structures in China

A review of the current situation and development of fire safety design for steel structures in China is given in this paper. Several codes and specifications used for fire safety design in China are introduced, and the present design methods are summarized. Then some research achievements on the behavior of steel structures at elevated temperature are presented. The achievements include materi...

Proposing the simplified model for choosing the method of retrofitting in existing structures against fire risk

Background and objective: According to the necessities in the part 3 of National Building Regulations, design and construction of buildings should be in a way that the structures, according to the type of use, the size and the number of floors, resist long enough to fire, and prevent from destruction of buildings or from spread of fire to adjacent spaces or buildings. For this purpose, it is ne...

An Energy Efficient AES Engine with DPA-Resistance

The advent of portable electronics which transmit and receive sensitive data via wireless communication have led to interest in the design of energy-efficient security engines. The hardware implementation of cryptographic algorithms, however, leaks side-channel information about the operations they process. Differential Power Analysis (DPA) is one of the most powerful attacks to disclose secret...
