The fi re-sealing gable wall(hereinafter referred to as fi re-sealing wall) in brilliant colors, diversifi ed forms and exaggerated shapes is a remarkable symbol of local dwellings. Originating from Fulao traditional vernacular dwelling and inheriting its advantages, fi re-sealing wall of Leizhou red-brick vernacular dwelling has shown diversity for the infl uence of immigrants, regional cultures, social background and economic status, and formed its own features in color, form and decoration. On the basis of fi eld investigation, this paper described diversifi ed features of the fi re-sealing wall of Leizhou red-brick vernacular dwelling, analyzed the causes of its diversity from the perspectives of aesthetics, function and technology, and explored the harmonious living philosophy implied by its function, form and art.展开更多

Through static test and finite element software analysis of comparing the panel zone with and without inclined stiffener. Some conclusions are given in the article. The load displacement curves show that the capacity of oblique nodes installed within stiffening rib components is enhanced i.e. 40% more than those without stiffening rib nodes. The results reveal that in the gabled frames, the corner node with the inclined stiffening rib can improve the bearing capacity of the specimens. When the extraterritorial flange is tension, the erection of the inclined stiffening rib can prevent structural failure and improve effectually the ductility of the structure.展开更多

The achievement of its themes and narrative skills has been greatly complimented by readers, especially its descriptions and analyses of the characters＇ psychological activities and their personalities. The notorious Salem Witch Trials of Hawthorne＇s family has a great effect on Hawthorne＇s formation of his views about the good and evil, the sin and penalty, and the psychological descriptive style in his works. In The House of the Seven Gables, Hawthorne takes this family history as the original writing background. Through exploring modem people＇s spiritual essence, using history as narrative original, Hawthorne＇s theme illustrates the past＇s influence on the present. By exploring the changes of the characters＇ psychologies and values, especially those of Holgrave, the narrator proposes a conception of general love to eradicate the actual contradictions. Hawthorne actually provides an alternative way--a nonpolitical solution to the national problems, which demonstrates not only his artistic pursuit but also his culturally political view in his writing. This paper consists of five parts.展开更多

However, by using two narrative voic?es simultaneously in the novel, an intradiegeitic one and an extradeigetic one, Hawthorne actually reveals his equal disapproval of both the Pycheon siblings and Holgrave. In the intradiegetic narrative, the narrative voice as a whole takes its side with Holgrave and reveals Pycheon siblings'isolation from the united struggle of mankind. In the extradiegetic narrative where the narrator ad?dresses directly to his readers, the narrator expresses a similar disapproval of Holgrave, who is equally isolated from the chain of hu?manity for lacking sympathy for his fellow beings. With the co-existence of two narrative voices, Hawthorne's true concern lies in calling attention to the equally dangerous situations of isolation from the chain of humanity:an isolation from the chain of progress and that of human sympathy.展开更多

The wind pressure distributions on gable roofs of low-rise buildings are investigated by a series of wind tunnel tests which consist of 99 test cases with various roof pitches, height-depth ratios and width-depth ratios. The block pressure coefficients and worst negative （block） pressure coefficients on different roof regions of low-rise buildings are proposed for the main structure and building envelope, respectively. The effects of roof pitch, height-depth ratio, and width-depth ratio on the pressure coefficients of each region are analyzed in detail. In addition, the pressure coefficients on the roofs for the main structure and building envelope are fitted according to roof pitch, height-depth ratio and width-depth ratio of the low-rise building. Meanwhile, the rationality of the fitting formulas is verified by comparing the fitting results with the codes of different countries. Lastly, the block pressure coefficients and worst negative pressure coefficients are recommended to guide the design of low-rise buildings in typhoon area and act as references for the future＇s modification of wind load codes.展开更多
