论违约精神损害赔偿

传统理论认为。精神损害赔偿适用于侵权民事责任，精神赔偿不能扩展到合同关系。随着社会的发展，英美法系和大陆法系国家的立法和司法支持了违约精神损害的赔偿请求。我国应借鉴国外立法经验，在违约之诉中有限度地承认精神损害赔偿。     

Seismic force modification factor for ductile structures

INTRODUCTION In codes for seismic design of buildings of many developed countries, elastic response spectra are adopted to calculate the base shear forces. For exam-ple, the base shear defined in Japan code 1997 is: FEK=DsFesC0ZAiRtW (1) where Rt is the elastic design spectrum; Ds is the structural coefficient changing among 0.25 to 0.50 to take account of different ductility of different struc-tures; W is the total weight of a structure; the others are site coefficient, irregular…     

地下结构抗震课程教学实践与探索

《地下结构抗震》课程是城市地下空间工程专业一门重要的专业课,是理论与工程实践密切联系的一门课程,要求学生通过学习,能够掌握地下结构抗震研究发展现状及趋势、地下结构的典型震害机理、地震工程的基本知识、地下结构抗震的设计理论和方法。本文通过对比分析“地下结构”和“地面建筑结构”的异同以及本科生先修专业基础课方面的不足,提出针对《地下结构抗震》课程的讲授方法,从形象化展示地下结构与地面建筑结构的区别;教学重点和教学方法调整;培养学生解决实际工程能力;坚持教学与科研一体化,相互促进、协调发展等四个方面详细展开,旨在改革传统的教学方法,有效提高教学质量。

Influence of freezing rate on cryo-damage of cementitious material

We report an experimental investigation on the impact of the freezing rate on the cryo-deformation and cryo-damage of cementitious materials. Saturated, dried and air-entrained mortar specimens are subjected to laboratory freeze-thaw cycles under three freezing rates without moisture exchange with the environment. In addition to basic mechanical properties and pore distribution, the measurement is also effectuated for freezing expansion, residual deformation of the specimens in each cycle. From the results it is observed that a high freezing rate does augment the freezing expansion of material while the cryo-damage is more important for a low freezing rate. Accordingly, both the freezing rate and freezing duration should be taken into account for the cyro-damage extent of cementitious materials.     

Use of probabilistic and deterministic measures to identify unfavorable earthquake records

This study introduces measures to identify resonant （concentration of energy in a single or a few frequencies） or unfavorable earthquake ground motions. Probabilistic measures based on the entropy rate and the geometric properties of the power spectral density function （PSDF） of the ground acceleration are developed first. Subsequently, deterministic measures for the frequency content of the ground acceleration are also developed. These measures are then used for identifying resonance and criticality in stochastic earthquake models and 110 acceleration records measured at rock, stiff, medium and soft soil sites. The unfavorable earthquake record for a given structure is defined as the record having a narrow frequency content and dominant frequency close to the structure fundamental natural frequency. Accordingly, the measures developed in this study may provide a basis for selecting records that are capable of producing the highest structural response. Numerical verifications are provided on damage caused to structures by identified resonant records.     

湖南省第七届民运会高脚竞速运动员损伤的调查与分析

运用问卷调查、文献资料和数理统计等研究方法,对湖南省第七届少数民族运动会高脚竞速运动员在训练、比赛中所产生的运动损伤情况进行追踪调查与分析。结果表明,高脚竞速主要损伤部位是手掌、拇指内侧、膝关节、足趾、踝关节及大小腿肌肉群等。分析认为,准备活动不充分、技术不正确或不熟练、运动负荷过大、身体疲劳、场地器材的不适合等是造成损伤的主要原因。建议从运动训练学、运动医学角度进行防治,最大限度地减少其发生率,将有助于高脚马运动水平的不断提高。     

站姿振动对血液粘度的影响

目的:探讨站姿振动和传统力量训练后,血液粘度的变化特征和生理学机制。方法:运动训练专业21名志愿者,在站姿振动或传统训练条件下,负重深蹲训练12周,测试血液粘度4次。结果:实验组的全血低切粘度、高频低振幅组的全血高切粘度、全血相对粘度和全血高切还原粘度明显增高,均与对照组差异显著。结论:站姿振动使血液粘度增大,其中高频低振幅振动的影响更早、更明显,应科学选择振动训练参数和提高医务监督能力。
