In slab column-shear wall structures,both the whole structure′s seismic behavior and failure mode are greatly influenced by the distribution of horizontal seismic forces between slab-column and shear *** this paper,a pushover analysis of topical slab column-shear wall structure was carried out,the seismic shear force that the slab-column and shear wall should undertake was worked out,the influences of plastic internal force redistribution and structure stiffness characteristic value on horizontal seismic distribution were studied and the calculation formula was *** analysis results showed that with the yield of the shear walls,the story shear force was undertaken by slab-columns correspondingly increased while with the decrease of characteristic value of stiffness of a structure,and the horizontal seismic force was undertaken by slab-columns correspondingly *** to the code,the design of horizontal force distribution may be cause insecurity problems,so it is necessary to give the distribution law of horizontal seismic forces in slab-column shear wall structures as the supplement to the corresponding regulation of the Code.

This paper focuses on the seismic resistance of one-storied factories, which are commonly used in China due to their flexibility, low cost, and short construction period. With the increasing demand for construction materials, these factories play a vital role in meeting the demands of urbanization and infrastructure development. The seismic resistance of these factories is critical to ensure safety, and this paper presents research on this topic. The paper highlights the advantages of one-storied factories, such as low maintenance cost and seismic resistance, and emphasizes the importance of conducting research on their seismic resistance to ensure safety in construction projects.

Objective： To evaluate the therapeutic efficacy of low-grade glioma （WHO grades Ⅰ-Ⅱ） patients treated with gamma knife radiosurgery and study on the efficacy evaluation method and radiobiological effect. Methods： 140 MRI data of 52 patients after gamma knife radiosurgery were analyzed in tumor size, necrosis or cyst formation, radiation-induced edema and MRI contrast enhancement and circumsciption change for therapeutic efficacy was evaluated. Results： The efficiency rate was 84.3%. The salient efficiency rates were 54.3% for total and 30%, 36.4%, 50%, 68%, 69.2%, and 73.1% for segmenting, respectively. Aggrandizement of tumor related to MRI contrast enhancement and necrosis or cyst formation. Radiation-induced oedema occurred for 32.7%. The MRI contrast enhancement occurred for 57.7% and showed special lace-like ring while some piece-like. Conclusion： Evaluation by MRI has showed gamma knife radiosurgery is efficient for low-grade glioma. The segmenting salient efficiency rate that increase with time is better for evaluation than the efficiency rate especially for long-term MRI follow-up. Radiobiological effect affect the efficacy evaluation. MRI contrast enhancement appears after therapy and shows special as lace-like ring and partly minificates or vanishes subsequently.
