ABSTRACT
The experiment specimen is a Tee-section reinforced concrete beam of 6 m long, with 5.8 m simply supported span. Laboratory experiments were conducted on this simulated bridge deck model with or without damage. The beam section is 500 mm high with 700 mm wide flange and 300 mm web thickness. The beam was resting on the top of two 412 mm high solid steel brackets connected to the concrete floor, as shown in Figure 1. The four-point loading system is used to create the crack damage in the prestressed concrete beam. The loading positions are 1/3 L and 2/3 L from the left end. L is the length of the concrete beam. The detail loading stages are listed in Table 1. Five displacement transducers and four load cells are used to monitor the loading procedure. Two of the four load cells monitor post-tensioned force and the rest monitor the applied loads. The data is recorded and saved to the computer by a data acquisition system. The sampling frequency is 1 Hz for each test.
