One With the Wind: A Comment on Strenger's (2004) "Of Potholes and Bends: A Meditation on Psychoanalysis and Motorcycle Riding".

Rightly, I believe, does Carlo Strenger (see record 2004-21113-014) focus on the need, in life and in psychoanalysis, to look forward and not backward, to trust that good and competent teachers will guide individuals until they can guide themselves. In motorcycle riding, such guidance, as Strenger makes clear, has its roots in a caring desire to help the neophyte motorcyclist--not unlike what a therapist must bring to his or her work. And, as is obvious, whom one selects as a coach, or analyst, is crucial; in motorcycling, one trusts one's very life to a teacher. Rightly does Strenger relate this capacity to trust to Winnicott's (and, I might add, Erikson's) understanding of a child's earliest relationships. In this short yet interesting meditation, Strenger takes us through the developmental stages of learning to master the motorcycle. (PsycINFO Database Record (c) 2010 APA, all rights reserved)

水下独立钢桩导向架的有限元强度分析

导向架用于水下独立桩在海上进行插桩作业时的导向及打桩时的扶正.在起吊和打桩过程中,导向架底座、立柱和支撑会受到各种力的作用,这些力将对其强度和结构设计产生重要影响.通过有限元计算,导向架底座的最大应力为161 MPa,前后方向立柱和斜撑的最大应力为64 MPa,左右方向立柱和斜撑的最大应力为158 MPa,这些值均小于材料的屈服极限,且从偏于安全的角度考虑,分析过程中没有考虑加筋板的实际结构,因此认为导向架的强度是满足要求的.     

Influence of the link overstrength factor on the seismic behaviour of eccentrically braced frames

The paper investigates the influence of the link overstrength factor on the seismic behaviour of eccentrically braced frames designed in accordance with capacity design principles. To this end, systems characterised by different level number and link length are designed according to the force-based approach, by either static or modal analysis. In order to correctly evaluate the ability of structures to develop global collapse mechanisms characterized by remarkable exploitation of the deformation capacity of links, incremental dynamic analyses are carried out with reference to either deterministic or random values of yield strength. While the first analyses are intended to lead to the conventional evaluation of the seismic response of EBFs, those referred to random values of yield strength are carried out to achieve a more correct verification of the capacity design principles and a deep comprehension of the sensitivity of the structural response to real strength distributions. On the basis of such results, the study also permits a critical analysis of the values of the behaviour factor generally proposed by building codes with reference to this structural typology.
