Improving the Reliability when Designing Formwork following Vietnam Standards

In Vietnam, the creation of separate standards for designing formwork to support and mould cat-in-site concrete has not been properly considered, so the calculation of design and the use of formwork is still limited and shortcoming. To help clarifying the problem, the paper conducts analysis, compares the current Vietnam standards for designing formwork to the standards of several other countries, which will focus on the content of determining the load and load combination when designing formwork. Based on the assessment and reference from the point of view of reliability, the results show the inadequacies in taking the load factor coefficients in the Vietnam standards, then suggest the adjustment coefficient of the load combination when designing formwork to ensure the safety of the structure. © 2018 Institute of Physics Publishing.
