Full‐Scale Load Testing of Selected RG4 Supporting BeamBPEX PROJECTMaptaphut, Rayong1 INTRODUCTION1.1 BACKGROUNDSeveral flexural cracks were observed in a RG4 reinforced concrete beam at line M8‐M10/ PE‐PF of level +11.500 TOS under service dead load condition. A number ofquestions asked with regard to the adequacy of the beam’s load‐carrying capacity. Inresponse to these questions, a full scale load test was carried out on BPEX projectsite in the premise of Daewoo Tech (Thailand), located at Maptaphut, Rayong on 27November 2008 to resolve the questions and concerns about the load‐carryingcapacity of the beam in a reliable and definitive manner. This report provides thetest results and their interpretation with regard to the performance of the beam incomparison with the ACI 318 code acceptance criteria.1.2 TEST OBJECTIVESThe objectives of carrying out full scale load test on the RG4 beam are:• To proof testing that the beam can resist working design loads in aserviceable fashion for which it had been designed.• To ascertain that the maximum deflections and crackings fall within limitsconsidered acceptable by ACI 318.To accomplish the objectives, the RG4 beam was load tested. ACI 318‐08 BuildingCode was used for testing protocols and acceptance criteria.1
