Referring to the cracks on the main pier of Hang Zhou Ningbo railway bridge during the construction, this paper presents a three-dimensional entity model to analyze the reasons for the cracks. The result of simulated calculation proves that the cracks on the main pier of railway bridge are induced by indirect effects, such as the temperature stress and shrinkage stress. The cracks have great harm...
Substantial precast panels of building structures were damaged by the Wechuan earthquake, while research in allusion to cracking precast panels on the reinforcement with CFRP is not sufficient, through the secondary load bearing experiment of 12 prestressed concrete hollow slabs, effects of the stickup methods and stickup amount on the reinforcement of prestressed concrete hollow slabs were studied...
The durable performance of the prefabricated panel building in Beijing was analyzed through the formatted questionnaire survey. Survey results showed that the majority of the respondent thought there was no or mild cracking, leakage, condensation & mould on the prefabricated concrete panel building. More than 75% percent of the respondents held a same above attitude. Which is much different...
Self-anchored suspension bridges are increasingly appreciated by engineers for their aesthetic look, low cost and more adaptive for geological environment than earth-anchored suspension bridges. Many self-anchored suspension bridges have been completed or are in construction in the world. For huge horizontal component of main cable force in the stiffening girder and the different construction method,...
