    STUDY ON PREDICTION DEFLECTION AT GIRDER MIDSPAN OF LARGE TONNAGE RIGID CONNECTION LEGS GANTRY CRANE BASED ON ENERGY METHOD by ZHANG DaPeng, CHENG WenMing, CAI Kun

    Published 2015-01-01
    “…It is the most important inspection index the deflection value of the gantry crane girder under rated load in the overall test.For large tonnage gantry crane in the overall test,prepared the experimental weight is often very difficult at the site,or even impossible perform test.In the text,it is deduced the girder deflection curve equation under the considering effects of the leg bending moment to the girder deflection When the concentrated load is applied to the position of the girder midspan.The girder deflection values can be obtained under three-small-loads at the girder midspan,and the coefficients of gantry frame girder flexural equation can be obtained.In this way,the deflection of the large tonnage gantry crane is predicted through the data of the three-small-loads method in the test.The three-small-loads method provides a practical and effective method for the prediction of the girder deflection of large tonnage gantry structure.…”

    Ship Load Response Test and Structural Bearing Capacity Assessment of High-Piled Wharfs by WANG Chengqiang, LIU Qiang, GAO Junjun, CHEN Zhonghua

    Published 2020-01-01
    “…Ship loads are most frequently exerted on wharf structures,which will inevitably cause different degrees of impact on the wharfs during berthing process of ships.In order to study the influence of the loads,this paper carries out field tests on the high-piled wharf in old ports of Lianyungang with different types of ship berthing loads,and re-checks and calculates the bearing capacity of the wharf according to relevant standards.It was found that structural response of the wharf to ship impacts is related with ship tonnage and berthing speed.In addition,the fender absorbing energy and ship collision force can be deduced according to fitting formulas.According to the results of field tests and re-checking calculation,the bearing capacity of pile foundation can meet the current functional requirements.…”
