Corrosion free, high strength-to-weight ratio enable CFRP composites to be a potential replacement for ordindary steel external tendons in engineering applications.
It is expected that failure mode of the beams is concrete crushing rather than tendon rupturing for engineering safety.
The ductility index of beams prestressed with external CFRP tendons defined on the energy concept can reach about 2.5 [4] , which can meet the requirement of engineering application. 0 20 40 60 80 100 120 0 40 80 120 160 200 Lo ad /k N Mid-span Deflection/mm RCB EB-30-N EB-30-S EB-45-N EB-35-S 0 200 400 600 800 1000 0 40 80 120 160 200 A C B Prestress Increment/MPa L oa d/ k N EB-45-N EB-30-N EB-35-S EB-30-S A 020 40 60 80 100 120 140 0 200 400 600 800 1000 P r e s t r e s s I n c r e m e n t / M P a Mid-Span Deflection/mm EB-45-N EB-30-N EB-35-S EB-30-S (a) Load-deflection curves (b) Load-prestress increment curves (c) Deflection-prestress increment curves Fig.3 Relationship of deflection, load and prestresse increment a) RCB b) EB-30- N c) EB-30-S Fig 4 Crack Distribution of Beams at Ultimate Tab.2

Through the comparative analysis of the precision of both the new formula and old one, the result indicated that the absolute mean square deviation and relative mean square deviation of new formula were less than 0.05mm/min and 5%,while old formula cannot meet the requirement ofoutdoor wastewater engineering design.
Therefore, it is necessary to calculatethe newstorm formula ofHScity according to currentrainfall data.This formulais going to provide reference for overall planningin HScity anddesignplan of local drainage engineering.
The results indicated that the new formula is able to meet the requirement of outdoor drainage engineering design while the error of old one cannot meet the requirement.
It isnecessary to evaluate the storm intensity formula, It is reasonable that evaluating storm formula, original stormformula for whether itis still applicable for the overall design plan of the city, the drainage professional planning and drainage engineering.

Application of Flexible Combine-Clamp in Digital Rapid Production for Aircraft Tube Xudong Xua Guangjun Li*b, Sheng Yuanc Manufacture Engineering Department,Chengdu Aircraft Industrial (Group) Co.
Introduction Just as blood vessels of human body, tube is the most important lifeline on modern military and civil aircraft, which transmits various kinds of media into engine, landing gear, cockpit, etc; meets the needs of systems such as aircraft fuel, hydraulic, environment control, etc.
Current Technology at Home and Abroad In 1985, foreign manufacturing developed the general flexible combine-clamp on the basis of special fixture, professional enterprises which were responsible for the development of the flexible combine-clamp appeared gradually, equipped with knowledge base and intelligent expert system[2], it is widely used in all kinds of manufacturing industry, such as engineering machinery, automobile industry and industrial pipeline, etc.[3] Since the 1960s, domestic manufacturing enterprises began to apply the flexible combine-clamp into the manufacturing procedure of turning, milling, planning and grinding, etc.
Implementation method Aiming at the existing problem of plane tube welding jig manufacturing, considering the multi-item and single-piece production during the period of new aircraft development, CATIA(three-dimensional design system) served as the platform, technology of knowledge engineering served as the means, many systems developed such as standard components parameterized modeling system, computer intelligent reasoning system, standard components replacement system, accuracy checking system and standard components management system, and also replace the traditional standard samples by three-dimensional model of tube, then realize the digital rapid design and manufacture of combined welding jig.
