It is shown by test verification that the FRP strength devotion factor used for this method is in accordance with actual conditions. FRP is not up to the ultimate strength when the concrete reaches the ultimate strength, whose strength devotion factor is in the range of 0.28 to 0.59, which is related to an elastic modulus. The method can be used to estimate axial compressive strength of the concrete strengthened with FRP. The theoretical strength is 10% to 30% higher than the measured one. The deviation comes mainly from a non-ideal bonding condition of FRP-concrete interfaces and discrete property of the testing data of compressive strength.展开更多

It focuses on her replacing reality with fantastic embodiments or illusion. She has taken unacceptable impulses into acceptable forms by unconsciously blocking the impulses such as superego and thereby reducing agony for the earlier traumatic experiences left indelible marks on her mind, and anxiety for survival. Her anxiety becomes too overwhelming that her ego urgently employs defense mechanisms to protect her. With her new hopes and dreams she desires to replace the highly stressful loss. Under mental and social stress, her illusion and her falsification of reality nevertheless became unable to overcome recurring trauma-causing situation in reality and her healing process thereby leaving her on the verge of extinction.展开更多
