Lantsoght, E.O.L. (author)As the existing bridge stock is aging, the task of assessing these bridges becomes increasingly important. One of the assessment methods for existing bridges is load testing. Improvements in the field of diagnostic load testing are related to the use of numerical models. Improvements in the field of proof load testing focus on the safety of...journal article 2023

Zarate Garnica, G.I. (author), Lantsoght, E.O.L. (author), Yang, Y. (author)Nowadays, with the aging of the bridges and the advancements in technology, load testing has emerged as an effective method to assess existing concrete bridges with missing information, or where analytical methods do not provide an accurate assessment. Two types of load tests are identified: diagnostic load tests and proof load tests. Both...journal article 2022

Faassen, Luuk (author)As the average age of bridges in the Netherlands is increasing and loads are rising, more research on the capacity of these bridges is required. One of the methods to determine if a bridge still has sufficient safety is proof load testing. Stop criteria are values of structural responses at which further loading may course irreversibly damage to...master thesis 2021

Lantsoght, E.O.L. (author), Yang, Y. (author), van der Veen, C. (author), Hordijk, D.A. (author), de Boer, A (author)Existing bridges with large uncertainties can be assessed with a proof load test. In a proof load test, a load representative of the factored live load is applied to the bridge at the critical position. If the bridge can carry this load without distress, the proof load test shows experimentally that the bridge fulfills the requirements of the...journal article 2019

Lantsoght, E.O.L. (author), De Boer, Ane (author), van der Veen, C. (author), Hordijk, D.A. (author)Proof load testing of existing reinforced concrete bridges is becoming increasingly important as the current bridge stock is aging. In a proof load test, a load that corresponds to the factored live load is applied to a bridge structure, to directly demonstrate that a bridge fulfills the code requirements. To optimize the procedures used in...journal article 2019

CHEN, Xin (author)Bridges with different geometrical configurations have been searched with linear finite element analysis. The aim is to find the position and value of critical proof load. Four different parameters, namely span length, width, skewness and thickness ratio, their influence on proof load are found. In total, 166 sets of data are obtained by...student report 2017

Lantsoght, E.O.L. (author), Koekkoek, R.T. (author), Hordijk, D.A. (author), de Boer, A. (author)Proof load tests of bridges can be very useful for structures with a lack of information, or for structures of which the effect of material degradation is difficult to assess. Contrary to diagnostic load testing, proof load testing is not welldefined in current standards in terms of required load and analysis of measurements. The risk...journal article 2017

Lantsoght, E.O.L. (author), van der Veen, C. (author), de Boer, A. (author)Proof loading of existing bridges is an option to study the capacity when crucial information about the structure is lacking. To define the loading criteria for proof load testing, a review of the literature has been made, finite element models of existing viaducts have been made, and on these viaducts, proof loading tests have been carried out....conference paper 2017

Lantsoght, E.O.L. (author), van der Veen, C. (author), de Boer, A. (author), Hordijk, D.A. (author)Proof load testing is part of the engineering practice, and can be particularly useful for the rating of existing bridges. This paper addresses how reliabilitybased concepts can be used in combination with proof load testing, and discusses how this approach differs from the current practice for proof load testing. Whereas the calculation...journal article 2017

Lantsoght, E.O.L. (author), van der Veen, C. (author), de Boer, A. (author), Hordijk, D.A. (author)Load testing of bridges is a practice that is as old as their construction. In the past, load testing gave the traveling public a feeling that a newly opened bridge is safe. Nowadays, the bridge stock in many countries is aging, and load testing is used for the assessment of existing bridges. This paper aims at giving an overview of the current...journal article 2017

(author)Proof load testing can be a suitable method to show that a bridge can carry the required loads from the code without distress. This paper addresses the preparation, execution, and analysis of a proof load test on a fourspan reinforced concrete solid slab bridge, viaduct de Beek. The bridge has one lane in each direction, but was restricted to a...conference paper 2017
