<p>This paper presents the design of two small footbridges in two different sites and economical contexts. The first footbridge, located in an urban site, is an arch made of Ultra-High-Performance Fibre-Reinforced Concrete (UHPFRC). The design technique combines the use of a contemporary material with the reappropriation of ancestral methods. The second footbridge, located in a remarkable natural site and made of weathering steel, presents both a tie-arch and truss structure. This minimalist conception leads to a “low- cost” structure.</p>

The permanent magnet generator has small size, simple structure, light weight, low cost, simple process, and eliminates the need for rectifier generator excitation windings and easy problems of the collector ring and brush devices, etc, are widely application. In recent years, a variety of good performance permanent magnet generators have been developed, but these generators are AC power output and generally low, when load changes the output voltage changes greater. Through the magnetism of permanent magnet generator, using good performance electronic components, a new type of intelligent electronic controller is developed; using the electronic regulator and the developed generator, the DC electrical power for vehicles required is solved.

Stitched laminates is a low-cost structure panels with carbon fiber face sheets, and through-the-thickness Kevlar stitching. Through-the thickness stitching is proposed to increase the interlaminar strength and damage tolerance of composite laminates. Tensile and shear experiment of stitched laminates at room temperature and in hygrothermal environment was carried out according to corresponding national standards. Experiment results indicate that the tensile and shear modulus and strength were much reduced by the stitching, especially in hygrothermal environment. Micrographs of fracture appearance showed that the exist of resin-rich area is the source of crack both in normal room temperature environment and hygrothermal environment. It is concluded that hygrothermal environment and initial crack in resin-rich area were prime reason for performance lost of stitched laminates.
