ESTIMATION OF FIRE TEMPERATURE RISE CURVES IN CONCRETE BUILDINGS (PART.2)

COST ESTIMATION OF HIGH PERFORMANCE CONCRETE (HPC) HIGH- RISE COMMERCIAL BUILDINGS BY NEURAL NETWORKS High-rise commercial buildings

Neural network approach is applied to establish relationships between the quantities/cost of the concrete/formwork, which is required for the structural elements of tall buildings using high performance concrete (HPC), and the design variables. Hybrid and hierarchical strategies are proposed for the cost estimation, where the feed-forward networks are adopted. After training, the neural network...

Towards Fragility Analysis for Concrete Buildings in Fire: Residual Capacity of Concrete Columns

Fire engineering a building, in general, has one central performance objective – life safety – and property protection is rarely explicitly considered. The engineering is typically based on only one possible fire, which may not represent the most onerous scenario (or may be much too onerous to be considered realistic). Taking inspiration from fragility analyses used in seismic engineering, this...

Advantages and Limitations of Precast Concrete Construction in High-rise Buildings: Hong Kong Case Studies

The Hong Kong construction industry heavily relies on conventional cast insitu construction involving extensive use of wet trades and on-site construction processes. The construction activities have been described as “labour intensive, dangerous and polluting”. Recently, the use of prefabrication has increased in the building industry. This paper presents the preliminary findings of an ongoing ...

Earthquake Loss Estimation for Reinforced Concrete Buildings: Some Problems

Capacity spectrum procedures developed for the assessment and strengthening of existing buildings have become the basis of methods for estimating potential post-earthquake losses which are today widely used in the insurance industry, and for urban risk mitigation programmes. The areas to which these methods are applied often contain (or largely consist of) reinforced concrete apartment building...
