Abstract: Sky view factor (SVF) is an important parameter which is being used to define the urban density in urban areas. In this study we investigated the correlation between SVF and surface temparatures of building facades’. For this purpose we implemented an application study on some specific points which exist on Gazi Street in Elazig on east side of Turkey and some branch streets connected to Gazi which have a remarkable structural density. In the study first we calculated SVF values of 2 points on Gazi Street which is east-west oriented 4 points on branch streets connecting to Gazi. Then we measured surface temperatures of building façades for choosen points for the hours between 8:00 am-16:00 pm. Rayman 1.2 program and fisheye photos were used to calculate SVF values. Surface temperatures were measured by infrared thermography method. Calculated SVF values for the two points on Gazi Street are 0.561 and 0.574 while the SVF values for branch streets ranges from 0.287 to 0.574. Higher surfa

Abstract: The purpose of this study is to compare Self Compacting Concrete (SCC) and Conventional Concrete (CC) which are used in beams with dense reinforcement, in terms of their apparent volume of permeable voids (AVPV). During the comparison of SCC and CC, the effects of two different factors were also investigated: strength class of concrete and curing condition. In the study, both SCC and CC were produced in three different strength classes (C25, C50 and C70) and the other parameter (i.e. curing condition) was determined as two levels: moisture and air curing. Beam dimensions were determined to be 200x250x3000 mm. The AVPV measurements were performed on core samples taken from the beams. Core samples of ø8x5 cm were taken from the beginning (0-100 cm), middle (100-200 cm) and end (200-300 cm) region of the beams according to the casting direction of SCC. In the study, AVPV experiments were performed according to Turkish Standard 3624. It was observed that, for both SCC and CC, AVPV values o
