Figure 18: Concrete top layer strain gauges arrangements; (M2). Figure 19: Concrete top layer strain gauges arrangements; (M3). More than 7488 readings were recorded by the data-logger during all different loading types and stages for all models (readings were recorded at every loading increment of w=4.413MPa and P=1.912kN for uniform and concentrated loads system respectively). The average of three readings for every strain gauge at each loading stage was considered. Fig. 20 simply illustrates the arrangement sketches of strain gauges sensors over all models.
