摘要：

A numerical method apt to analyse compact cross-sections of general shape under bending, compression and given non-linear strain distributions of general shape is presented. The method can take into account holonomic hardening or perfectly plastic constitutive models of generic shape. The proposed method is implemented in a computer program permitting the analysis of the effect of the non-linear thermal loads (owing to daily and seasonal changes in shade air temperature, solar radiation, re-radiation, etc.) on the cross-section behaviour of reinforced concrete or prestressed concrete bridge decks, roof planks and slab, reinforced either with steel or with carbon, aramid or glass fibre reinforced polymers. The results of this work lead to the proposal of some practical design rules. (C) 2004 Elsevier Ltd. All rights reserved.
